People just love to discuss EU4 idea groups, and to be honest almost everything they say is completely wrong.
I have no intention of joining this making stuff up contest, so instead here's a ranking that's as close to correct as it's possible to get.
The algorithm not only gives meaningful relative rankings, it gives meaningful absolute values - expressed in monarch points.
I've written it a while ago, but I'm posting it now, as next patch will mess with the values.
The Algorithm and its limitations
Value of +1 monarch point per month is 1, and that's the unit everything is expressed in. As dip/adm are far more valuable than mil, they're both worth 1.1 and mil is just 0.8, so they average to correct value.The game has huge number of bonuses, and they're reduced to other bonuses based on some sensible assumptions. Algorithm has simple models of income, spending, military power, envoy use, monarch point budget and so on, and given such assumptions vast number of bonuses can be reduced to just a few.
The ranking has serious limitations, which are completely unavoidable:
- Assumptions used to calculate point values are based on a typical country, at typical point in the game - maybe extra colonists wouldn't be much use for you as Ulm and maybe you really value galley combat strength over everything else as 1444 Byzantium, but ranking merely expresses how good those bonuses would be on average
- Algorithm is completely linear. It tries to estimate how good +1 of some bonus would be, and makes linear extrapolation from there. Some bonuses are better in multiples (-10% galley cost is weak, but -100% galley cost is pure exploit territory), some are weaker in multiples (like you really need that 6th missionary most of the time), the algorithm just tries to estimate how much value would an extra one have for a typical country. The game is helpfully linear, so two +10% bonuses are identical to +20% bonus, but that's not the same as being twice as good.
- Algorithm for the same reason ignores any synergies or anti-synergies between different bonuses.
- Algorithm just focuses on bonuses, it ignores all events, decisions etc. based on idea groups.
- Algorithm ignores order of bonuses, so it doesn't care if good ones are early or late.
There are also limitations which could be improved upon:
- Assumptions and numbers are reasonable ballpark estimates, but they don't have amazing precisions, and you could easily tweak them getting somewhat different rankings.
- After we reduce handful of bonuses to some values like "5% higher income", "10% more powerful armies", or "1 extra diplomat", how do they compare with universal unit of +1 monarch point/month? Numbers I've chosen here could definitely be challenged.
- There is not enough distinction made between "X" and "base X". For many things it's just fine, but "trade income" and "base trade income" are typically quite far from each other, so good ballpark estimate of trade income would still give wrong estimates of how much trade income bonuses are worth, as they apply to base trade income instead.
- There could be bugs.
Fortunately it turns out that numbers algorithm returns are not even close - some ideas are drastically better than some others, which makes worries about precision less important.
A few examples
The whole algorithm is on github. Here I'll just present some examples of the kind of reasoning it uses.
Algorithm estimates that typical country spends 40% of its budget on land forces, and 50% of its army budget on infantry, so -10% infantry cost is equal to -4% army cost, or +2% extra money.
Algorithm estimates that you'll be hitting +1 stability button once every 15 years, and its base cost is 100 (actual cost is irrelevant due to how bonuses stack). So -X% stability cost bonus is worth +X adm points every 180 months. In other words -10% stability cost is estimated as +0.055 monthly admin or +0.061 average monarch point (as adm mp is worth 1.1 mp).
Algorithm calculates that throughout the game you'll spend 4 points a month for base cost of techs - this is surprisingly robust, as we know how many years there are in game, how many techs start to end, and what it's base cost (600/tech). It doesn't need to know how much you're paying for actual techs, bonuses are applied to base cost. So -10% tech cost is worth as much as +0.4 bonus to each monarch point, or +1.2 points/month total.
Algorithm estimates that diplomats spend 25% of their time travelling, colonist 10%, and merchants 1% (missionaries just teleport), and average country has 2 diplomats, 2 merchants, and 1 colonist, so -X% envoy travel time is comparable to +2 * 25% * X% diplomat, +2 * 1% * X% merchant, and +1 * 10% * X% colonists.
Algorithm estimates that usually stability is what you'll be using papal points for, so 100 papal points is about as good as 100 adm. Then it converts +1 yearly papal points to +1/12 montly adm points, and takes 50% as good guestimates how likely you are to be able to take advantage of that. That 50% is somewhat dubious, as much fewer than 50% of countries are Catholic, but typically European countries get this kind of bonuses.
Algorithm estimates that for a typical country, 25% of infidel provinces are heretics, and 75% are heathens, so +1% missionary strength against heretics is worth as much as +0.25% against everyone.
Algorithm estimates that extra siege pip speeds up sieges by 17% (that's based on some spreadsheet simulations), and 30% of sieges have leaders (that's just a guess), so +1 leader siege is worth 5.1% siege ability.
If you're interested in such calculations, script explains its choices in comments pretty well.
And it all reduces to...
The last step is most arbitrary, covering all things that have no good conversions:
- +1 colonist - +3 points
- +1 diplomat - +2 points
- +1 missionary - +1 point
- +1 merchant - +1 point
- +1% missionary strength - +1 point
- -1 unrest - +1 point
- -0.1 autonomy - +1 point
- -10% warscore cost - +1 point
- +10% money - +1 point
- +20% siege ability - +1 point
- +10% defensiveness - +0.1 point
- +10% military power - +1 point
- +10% manpower - +0.3 point
- +25 colonial growth - +1 point
- +0.5 point for every minor ability (like infiltrate administration, reduced stab impact etc.)
- +1 point for extra CB (religious CBs are treated as 2 different CBs)
- +1 annual legitimacy - +0.5 point
- +1 annual republican tradition - +1 point
- ability to explore - +2 points
- +1 advisor pool size - +1 point
- +1% hostile attrition - +1 point
- 10% better relations over time - 0.2 points
- -10% AE impact - 0.2 points
- +1 diplo rep - +1 point
A lot of bonuses like prestige, IA, fervor, heir chance, trade range, interest, ship recruitment speed, enemy core creation, spy offence etc. are ignored completely as either far too situational to be of use to a typical country, or basically pointless.
To help with those numbers I took decisions and policies like "+1 missionary strength +1 unrest" (maybe yes, maybe no - so these bonuses are worth about the same), "+1 colonist for -1 dip" (so ridiculously good so they removed it in patch), which is not terribly scientific, but it's a good starting point.
Idea groups
And here's the ranking of idea groups:
- 11.76 Exploration Ideas
- 9.54 Religious Ideas
- 8.23 Diplomatic Ideas
- 7.58 Expansion Ideas
- 5.22 Humanist Ideas
- 4.80 Influence Ideas
- 4.50 Plutocratic Ideas
- 4.14 Trade Ideas
- 4.10 Aristocratic Ideas

- 2.40 Offensive Ideas
- 1.94 Economic Ideas
- 1.66 Administrative Ideas
- 1.35 Quality Ideas
- 0.96 Maritime Ideas
- 0.56 Naval Ideas
As you can see every single military idea is total crap, and naval/maritime are just ridiculously bad. I don't expect anybody to possibly be surprised by top 5.
National ideas
And here's the ranking. Personally I'd value Russian, Spanish and American ideas above Najdi - Najdi ideas are very good, but its +5% missionary strength is perhaps not worth 5x as much as +1% missionary strength bonus would be, so algorithm's linear character arguably overestimates it.
Only one country has ideas which algorithm estimates as (within margin of error) worse than default ideas, and I totally agree with this assessment.

Your flat values are just flawed.
Colonist should be at best 2, and diplomat at best 1,5.
You should have realised something went horribly wrong when espionage wasnt in last 3.
Anonymous: I'm aware that internet thinks espionage is awful and military ideas are amazing, but calculations say otherwise, and I trust calculations.
Weight changes you mentioned are reasonable, but they wouldn't really change ranking that much.
It's so cool that there's even an algorithm used. I'm glad that my teacher who teaches me polish using Skype at http://preply.com/en/polish-by-skype mentioned this. I totally agree with the ranking.
Really cool concept but the other anon has a point. The flat values grossly overvalue diplomats and undervalue manpower, morale and discipline.
Really cool idea but i guess the problem is raking idea groups without context - exploration may be good, but in some situations its useless. From my perspective when you're talking about which are the better idea groups you're looking for the ones that hold the most value regardless of the situation you are in, which is why the military ones tend to be the ones that stand out. Similarly some idea groups kind of overlap to the point in which it would be detrimental to take both of them, Religious and Humanist for example, and in those cases the weaker idea group becomes significantly less optimal.
Also, you can't defend espionage and not try to back it up :P. I cannot see how its a case of people hating it more than it deserves, I've tried to find the vaule but those ideas are useless.
And in case you're wondering, its a tie between religious and quantity for the best idea group, regardless of the situation they are both incredible and they are probably the only two idea groups that don't have something completely awful tucked inside them somewhere.
Great attempt on summarizing it all, but there are some really serious flaws to the values.
For instance modifying papal influence by a chance to be a catholic has no logic, since every nation having this is catholic. Also on the same note - stab costs 100 if not modified, the further stability over 1 cost much more and those are the ones you spend your papal influence on - hence its value is amore than a bit off.
Advisor pool +1 cost equals one point? Really? I never found it even remotely useful.
Missionary equals one missionary strength? Now this is completely wtf. This is true only if your positive missionary strength is equal to the number of missionairies, which is likely never. Also these two are extremely interdependent.
But especially, all your claims about military being useless are based on making 10 percent increase worth 1 point. This is really ludicrous. I mean, seriously, do you think that having two diplomats a two diplomatic reputation is worth having 60 percent stronger armies? Is there any argument you can base this assesment on?
I disagree with MIL MP being the least valuable. A single MIL tech advantage can win battles and even wars for you. Especially the ones that give boost in both morale and tactics. For instance, tech 4 Korea can single-handedly take on tech 3 Ming. That's how important MIL MP is. Dip MP should've been the one with 0.8 value. There's no other use for it aside of reducing WE and annexing vassals, and usually your provinces end up with high production points because there's no other way to spend that overflowing DIP points.
is there Moluccan ideas?
Valuing a diplomat as greater than a merchant and missionary is your first red flag. You devalue millitary conquest in favor of colonization, but a more effective strategy is stealing the colonies from weaker colonizers. A formula like this is illogical, because scenarios and events play such a huge role in their value. France colonizing is illogical when you can conquest throughout Europe and beatup on the colonizers. What are the Turks or Ulm going to do with a colonist? Even if the Turks switched spots with portugual, the stacking of core cost reduction makes administrative and military ideas optimal for them. Synergy and focus is everything.
Also, Dip is not equal to admin and sword mana is at least on par with bird mana.
And how can you value yearly legitimacy as 0.5, but not even count prestige/from land battles? Prestige is what causes the (less valuable) legitimacy grow.
And admin is the best (one of) because the amount of admin it saves you.
Sorry but this ranking is kind bs. Great that you made some kind of algorythm but the best ideas are the ones that are usefull to your style of playing. For example, you value exploration ideas very high but to me they are useless. Why? Because I don't usually play the collonization game. I prefer the good old warfare, therefore the best ideas for me are the military ones. The same goes with national ideas. NI that focus on collonization are basicaly useless to me. Once again the best ideas are the ones that suit your playstyle.
Anonymous: The ranking weights can be adjusted based on playstyle, but the results are pretty much the same - you get far stronger army by blobbing more efficiently (by colonizing, coring faster, diploannexing faster, avoiding coalitions etc.) than from minor bonuses provided military ideas.
The ranking here is for very old version of the game, but it didn't change that much.
Here is a good test for this algorithm and the reason I think it is utter bollocks. Let's say two relatively evenly matched countries go toe to toe, not one takes tim top 8 ideas and the other takes the bottom 8. I think these two nations should be Tunis(last 8) and Morocco (first 8). Tunis would simply roflstomp Morocco because Tunis would have all the military ideas. The problem is this algorithm has no idea what opportunity cost is. For every non mil related idea group, you miss out on mil mil bonuses which another nation could take and gain an advantage.
Ben Grosz: If you gave Ottomans generic ideas, and Bosnia all the military ideas, Ottomans would roflstomp Bosnia anyway.
Anyway, unless you're talking Jan Mayen, most military bonuses from ideas are really low. Being bigger, or having more sword mana (so extra mil tech) is generally worth far more than those tiny idea bonuses.
You say this while also devaluing Administrative ideas to a ridiculous degree. Administrative points are ALWAYS the biggest factor in preventing expansion, with the second being manpower, another thing you severely underestimate. Coalitions are annoying,but only a REAL problem in the Holy Roman Empire where AE is multiplied to an insane degree. Money is never a problem as taking loans to fund wars where both land and money are taken is always profitable, and, even when it isn't, loans are never a problem and usually beneficial.
Missionary strength being valued the same as a missionary, as another person pointed out, is insane. If your missionary strength is higher than 1 (which it always is), then a second missionary is more efficient.
Another huge issue with this is something you acknowledge yourself. Najd, Spanish, and Byzantine ideas are SEVERELY overvalued because missionary strength is less valuable the larger the value is. This also ignores conflicting ideas. Tolerance of heretics/heathens is rarely useful when combined with missionary strength.
Things like hostile attrition and increased advisor pools are practically worthless (the former only so in a single player campaign, but that's the only way you could rate military ideas so low), yet you rank both of them as equal to things like missionaries and MORE than things like manpower.
You should have realized your algorithm was garbage when things like espionage rank higher than quantity and administrative.
Also, it ignores that military ideas (like morale and discipline) can be necessary for early game expansion, the most important phase of the game
Anonymous: First, the disclaimer. This ranking is based on a version that's 3 years old now, so many things which used to be a lot more valuable back then. For examples:
* there was no way to reroll advisors or ask estates, so if you wanted specific one (like missionary strength or diplo relations or unrest) you were completely at mercy of the RNG. Or at best you'd get a level 3 you couldn't afford, or level 1 which basically cost your infinite money empire -2 power/month if you wanted the bonus.
* there were fewer ways to get missionary strength (no estates, no way to accept cultures at will, no reliable way to get inquisitors except slow RNG)
* hostile attrition was very important before current super low 5% attrition cap
* there was no free diplomat from being kingdom+, so diplomat from ideas was extremely valuable
* back then proper way to expand was mixing coring and diploannexations about equally, so admin wasn't actually all that helpful (and that extra diplomat was a lot more important than now)
For most recent rankings (which still needs a few tweaks around things like embracement cost etc.), it's:
10.63 Exploration Ideas
6.62 Diplomatic Ideas
5.92 Expansion Ideas
5.39 Humanist Ideas
5.32 Religious Ideas
4.66 Influence Ideas
3.87 Administrative Ideas
3.67 Plutocratic Ideas
3.59 Innovative Ideas
3.49 Aristocratic Ideas
3.45 Defensive Ideas
2.74 Quantity Ideas
2.74 Offensive Ideas
2.69 Quality Ideas
2.24 Trade Ideas
1.36 Economic Ideas
1.25 Espionage Ideas
0.84 Maritime Ideas
0.81 Naval Ideas
Now for some more specific points where you're wrong for even current patch:
* the algorithm inherently based on judging ideas separately, some synergize (like religious and exploration, which gives you free great CB for whole world), some anti-synergize (like religious and humanist).
* the algorithm assumes fairly representative gameplay, in particular fairly heavy blobbing but nowhere near WC levels - if you're going for WC then administrative ideas are a lot more important
* missionary strength vs missionaries - if you already have 2 missionaries and average strength of 2%, then extra missionary and extra point of missionary strength are of equal value (3x2% or 2x3%). Both those numbers depend on religion you play as and part of the world where you play, but if it wasn't for free inquisitor from estates they'd be about comparable.
* military idea groups are mostly garbage overrated by the beginners. Early game your 10k stack with ideas fights as well as your opponent's 11k stack without ideas. And then you still can't take as much land as you want or half of Europe would coalition you and wipe you out either way. Number of campaigns where this tiny advantage matters is basically zero, it just lets you be a bit more sloppy. Things which are bottlenecks like admin points, dip points, AE, unrest modifiers (to tank more OE), siege speed modifiers, gold for merc spam etc. don't care about your morale modifiers.
* in particular if you think morale is important, I'd recommend checking out Reman's combat tutorials for beginners - https://www.youtube.com/channel/UC7p-t_rMi9UrhWMeL-MGM2Q/featured
The problem with that is the extra bonus provided by advisors is only their secondary purpose. Their primary purpose is extra monarch points. Mana is difficult to come by. Mana is the most valuable resource in the game. Expansion is halted entirely by a lack of admin. If you're behind on military tech, you can't hope to stand up to opposing militaries. Diplo tech is often less important, but it's got a few uses outside of tech. Grabbing up the extra missionary strength advisor is nice yeah, but it's generally unimportant because you've either already taken religious or humanist and hence don't need it, or it's early game and you likely don't need it all that much (unless you're a muslim sultanate in India, I guess).
The rest of your "the algorithm is outdated points are fine or I'm simply unable to comment on from lack of experience.
I recognize that your algorithm judges ideas separately.
What is "fairly representative gameplay"? Conquering the entirety of Europe as Ulm? Conquering a good chunk of Europe as France? Conquering Iberia and France as Spain? You can't simply assert that your algorithm represents fairly representative gameplay when you can't even define fairly representative gameplay.
Missionary strength is rarely as valuable as another missionary. I'm not sure what game your playing when you only have a missionary strength of 2, but it's certainly not EU4. You're missionary strength=missionary claim only works when your missionary strength is equal to your number of missionaries, and, again,if this is true, you've screwed up.
You're overstating how overrated morale and discipline are rated by a longshot, but, generally, you're right, they make little to no difference in an actual battle. So why do I value military ideas? Manpower. Be it national manpower, manpower recovery speed, land force limit (in the early game), or mercenary cost and availability, all help to increase and restore manpower. But another problem is losing manpower. How do you avoid that? I'm glad you asked, through discipline and other combat modifiers.
Thanks for the recommendation, but I've already seen the video. What I find ironic is that Mr. Reman is a proponent of military ideas, especially quantity, my personal favorite too.
Also, haven't you ever seen a Prussian Space Marine corps stackwipe an army four times its size? Obviously, this is unnecessary over kill, but the point is that combat modifiers obviously make a huge difference, especially late game when combat width is nearly always filled to it's entirety.
Most of the assumptions in the algorithm such as blobbing rate are explicitly specified and can be tweaked. It's command line script (and it requires copy of the game to work), so it's not the easiest thing. I thought about putting it online, with some sliders for adjusting assumptions.
You can check assumptions in code comments https://github.com/taw/paradox-tools/blob/master/analysis_eu4/bonus_scoring.rb
Some of them might be outdated by now, or could use some tweaking. It usually doesn't make a huge difference.
Prussian Space Marines stuff mostly only happens when facing army with really bad composition (like AI inf-only merc spam stacks once it ran out of normal troops), catching them drilling, surprise blocking retreat etc., and really has little to do with combat modifiers. In overwhelming majority of usual cases enemy will just shattered retreat after losing battle.
As for manpower etc. you can ideas for more manpower, or you can use ideas for stronger army (lower attrition, higher damage per unit), or you can blob harder, or you can get more gold and merc spam, or you can even get building cost discount and spam manpower buildings etc. There's a lot of approaches to it.
And I'm not disputing that under current patch (with Cossacks DLC), average missionary strength is generally much higher than average number of missionaries, at least for Christian countries.
"but calculations say otherwise, and I trust calculations."
Calculations based on completely subjective, arbitrary assumptions, that make no sense?
Anonymous: All assumptions are explicit in the code. I'm totally open to discussing assumptions, or to any fixes to formulas (like the one about missionary strength vs extra missionaries, where the commenter was right for current game version), but very few people ever do that - they just "know" that something is good or not, and base it on absolutely nothing.
First of all great work. I usually take at least 2-3 mil ideas and was about to disagree until you mentioned "Being bigger, or having more sword mana (so extra mil tech) is generally worth far more than those tiny idea bonuses." Being one mil tech ahead is much more important than having more discipline and morale. I choose to trust calculations too.
I also think that ranking ideas between their own groups (adm, dip, mil) is a good idea. If I have a 0-0-6 ruler than I'll probably pick a military idea anyway.
Garbage in, garbage out.
