Just like regular people, scientists can make stupid decisions too!
But seriously this has more to do with the fact these kids who are doing these 'scientific' studies are more likely to be loners who don't fit in and who are probably angry at society about it (yeah I've been there too) and they find a group of people (usually on social media) who are like "Hey we get you, we're just like you! Come talk to us, we're your friends" After a bit of conditioning and peer pressure from their new friends who have told the "real truth" and how to fix the world through violence. Most gangs and cults work like this, and this approach works well on socially awkward loners with little to no friends.
In short just because they were studying science doesn't make them any less human then anyone else, just as gullible and foolish as the rest of society.
