Pillars of Eternity

Disposition is the player’s “reputation” based on personality and choices that will create NPC interactions. There are ten personality types for NPCs, and the player’s reactions to them generate disposition.

You increase your disposition by talking and acting in quests and dialogue. There are three ranks to attain and each is tracked individually – you can have several dispositions going on simultaneously. Each rank is met when a certain amount of points are gathered – and you gather points depending on the event. A minor option gives a measly 1 point, average is 3 and major is 7.

Rank 1 requires 25 points, Rank 2: 50, and Rank 3: 75 points.
Here are the possible dispositions, gain ranks by keeping to a certain type until you earn it, then move on:

Aggressive – Hot-headed, bold, or impatient.
Benevolent – Charitable, kind, soft, or weak.
Clever – Sarcastic, sassy, foppish, or irreverent.
Cruel – Merciless, sadistic, brutal, or imperious.
Deceptive – Dishonest, manipulative, or shrewd.
Diplomatic – Cautious, tame, or courteous.
Honest – Guileless, sincere, or straightforward.
Passionate – Zealous, romantic, or obsessive.
Rational – Practical, standoffish, or cold.
Stoic – Tight-lipped, cool-headed, or simple-minded.

you should earn this naturally through game play however There is a very easy way to see which dialogue options affect the disposition.

Press , select Difficulty, now Check the Box which says Show personality/Reputation. This will then show the consequence on personality by every dialogue option. This is very handy .
