Have the perfect argument 100% of the time.
Every emotion weakness has 2 possible correct answers a “Strong argument” and a “Perfect Argument” they will shift back and forth between those 2 for any persuasion mini game. This means that if you pick aggressive on a “withdrawn” weakness during your preparation and it got highlighted as “Strong Argument” (light green glow) then the perfect argument is “manipulate” and vice versa.
You can also use this to try to figure out what the hidden weakness is without paying. For example, if you guess manipulate and the game says it’s a weak argument then you know that it’s not Attached, Withdrawn, or Oversensitive. Leaving you with a possible Bull Headed, Carefree, and no opinion and if you’ve read the character descriptions you can figure out which is the hidden weakness.
Withdrawn – Manipulate/Aggressive
Oversensitive – Humility/Manipulate
No Opinion – Careless/Aggression
Attached – Manipulate/Careless
Bull Headed – Humility/Aggression
Carefree – Careless/Humility
I have finished the game and ever since I figured this I’ve had 100% success in the interrogation scenes. Knowing this does make the game easier and kinda detracts from it IMO so use at your own risk.
If I remember, ill add screenshots of these in action.
