In quite a few countries, Schools do not teach people to think . They build up a mindset in people .
Sometimes subtle but sometimes it's in your face

But approx. 30 years ago, that was also the case (imo a lot less). Looking back, some of the school-projects or themed weeks were dubious.
My experiences really depends on the teacher itself, a lot were very open to discussions and critical thinking (as they explained: you learn more when you discuss the material) but some just "force" their opinion, even leaving out chapters to support their view on that matter.
On elementary school, 1 teacher sometimes excluded some kids from fun activities because he disagreed with certain upbringing choices.
For news:
Some networks tell you what a person did in a press conference and another will show the actual footage. And some translate "might/could be" to an actual fact.
They determine what happened, throw out all the data that doesn't fit their conclusion, and then present their "fact" as the only possible conclusion.
It happens to both sides of the argument, if i'm really interested into something I'll check multiple sources or check the original footage.
But with the whole vaccine/anti-vaxx situation, one of my close friends is very anti-COVID19 vaccine. When you go looking for it, you will find supporting "info" on any thought. He fully believes a youtuber but i question everyone who claims they are an expert on all fields on medications, engineering, environment, economy and politics. I think most people do
You can debunk almost everything he says, some comments have a truth element but it's corrupted with inaccuracies.
It's weird to see someone go from
only anti-covid19 vaccine to a complete conspiracy nut. Luckily not Qanon but pretty much anything debatable that happened in the past 20 years.
Millions of people have taken a vaccine. Only few people have experienced issues (sorry for the people who suffer that) but hopefully soon i'll get my notification for a vaccine.
I'll get a vaccine because especially when it comes to vaccines - i believe in the "greater good" aspect. History has shown vaccines have (almost) eradicated or control certain diseases.
