The highlighted part is actually a Ti description. Te users make fast and efficient decisions. Although I must say, ESTJs do indeed tend to stop and think for a brief moment before adjusting their initial opinion. But I don't think they actually (re)build opinions in their minds from scratch (=Ti), instead they reprocess their analysis of a situation based on new information, using an existing model with different facts/data (= Te+Si).He's a very logical, thoughtful person. He's never afraid to share his opinions, though he takes time to form them and backs them up with facts. So he doesn't tend to give an opinion at all unless he's researched the facts first. (Which made me think he was an introvert at first, but now I don't know.) He's usually pretty calm and collected, at least when I've seen him, and he's super studious and dedicated to school and his hobby (mechanics ... basically planes, trains, and automobiles, if you will; he loves them). His life is super mapped out (wants to be a lawyer, has a financial plan for college).
