More than that, they're just stupid.
Here's just one example of dumb Jedi stuff. I just rewatched the prequels and it occurred to me, that Anakin didn't really suddenly turn to the dark side because his mom died. He turned to the dark side because he didn't have any friends to check him when he's being a douche bag... The dude literally has nobody to talk to except for Padma, and he's forbidden from pursuing a romantic relationship with her, which is super frustrating. This is a scenario destined for failure. What he really needs are some friends he can talk to and vent at about his shitty situation.
Here's the weird thing though, remember that scene where Yoda is training a whole class of little padawans? Those padawans at least have a cohort, they have a group they can bond with and lean on as they grow up and continue their training. So if that's the way they run things, where is Anakin's cohort? Why is he isolated? Anakin has a single person as his mentor, boss, teacher, therapist, dad and only friend, that's not really healthy. And when that one person is gone for an extended period, that leaves Anakin with absolutely no support structure and a lot of temptation to make bad choices, this is setting him up for failure. Cause let's be honest, he's a teen, making bad choices is what they do.
I was 12 when my dad gave me the talk (the talk about how police will kill you if you aren't exceptionally polite to them). How having skin our color is very dangerous because police are afraid of us. So no quick movements.
