Why him? Why here by Helen Fisher

[Jani]

Everybody sees me as a pussy, bad body language, always looking down to the ground, not assertive,... The last year is that changing, because I'm now living proactive.
But, I'm VERY competitive in sport games (basketball, football, soccer,...). The moment that the game is on I'm willing to die to win. I don't care how much it will take, I don't care how many times they beat me down to the ground, I don't care how big the opponents are, I don't care that I'm not standing a chance,... No matter what, I will put 120% of capabilities and passion in the game. During a game I'm a beast, assertive, great body language, confidence,...

No one person has ever expected that, what is a great thing because they think that they can walk over me like off the field. BULLSHIT!!

MBTI can't predict that, and I have many more examples that's just the most extreme.
SNAP can predict that. SNAP uses primary and secondary influence factors that changes depending on the situation to predict your behavior.
The input you get from the world changes, so it's logical that your output (behavior) will vary from moment to moment.
