Principle #2 Learn from multiple formats or methods. When you are curious about something, you want to know everything you know about that subject
Well, something that I criticize a lot is people who don't put a little effort into searching/learning things they have doubt for. Like we have A LOT of ways to get information almost everything on the internet, and besides there are things full of trash, with a little curiosity, we can get well informed.
The best thing about it is that you can have your own opinion about things.
That couldn't be far from the truth. Generic information available widely and even plenty research papers are available online. All it takes to confirm whether a something is false or not is only a mere seconds. Yet, plenty are still falling to false information. But yeah, I think there's a lot factor at play when it comes to learning for instance socio-economic situation. Even today, there are plenty who still doesn't have a smartphone is actually struggling with remote studying during the pandemic.
