Any examples?

Economics, business, healthcare, nutrition, education, and then a list of hundreds of disciplines that are internal to each of those broader categories. Economics seems to be the worst by far, probably followed closely by healthcare and medicine. There could not be a more clear "report card" today showing the results of the two failed ideologies these are built on as well.
my teachers, after me studying economics for 4 years:
Don't confuse the way that economics is perverted by politicians and the actual practitioners of the discipline. For example, very few actual economists (even among those on the left) would tell you that protectionist tariffs or price controls will end well. That doesn't stop politicians from finding a few misguided souls that will shill a policy like that.
This short book beautifully lays out what went wrong with economics and what the right way is from the most foundational principles.
To be fair Economics and other disciplines are ever evolving and those who gained advanced understanding through formal education will likely not be satisfied to the point they will stop learning and keeping up with those changes.
The best metaphor I can improvise right now is that of someone who is coached to become a good surfer by great surfers through daily lessons and someone who watches youtube videos and then hits the waves.
It will depend on things like weather or tide but my money is on someone who practices constantly and dedicated enough time. Yes, academia and youtube can prepare you, but you have to do serious work to gain best understanding and keep updating oneself.
