There is a reason why many persons cannot make informed decisions and it depends on the situation whether one factor is involved or many. For instance, those with executive function and/or cognitive difficulties can have problems with regards to judgement, planning, prioritization, organization, details and in the initiation and completion of tasks. As well, anyone who has severe issues related to impatience/ impulsiveness, attention/concentration, procrastination, or with regards to black and white thinking or who has any other condition or trait involving extreme anxiety, fear, anger, lack of trust/suspiciousness, an inability to pick up on nonverbal cues or other issues, they have could have difficulties seeing all the benefits and consequences of some of their decisions, if not a strong hyperfocus of interest, thus at times making the wrong decision. In my case, I am "now" the opposite there. I nitpick every detail, weigh every fact versus opinion, look beneath the surface, have much patience, look for any hidden things and inconsistencies, research things when not enough info is given, consider all perspectives/pathways etc. before making any decision.
