It seems to imply that the only valid way to accrue knowledge is by going to the high priests at the university systems and performing the sacred study rituals because self obviously this is the one true way of producing knowledge.
Should i put my hand into an open flame? I dont know,tough to say without performing a meta study of existing flame temperature studies to confirm what the best journals think. otherwise theres just no way to know so I'll just have to test it out.
Im not against science or the scientific method. In fact im extremely pro. but it's not the only way to come come valid conclusions about things.
im going to go ahead and suggest that on average learning about finance is going to be helpful for people to manage their finances. call me a crackpot but It's not particularly important for me to verify this belief with a study.
and all of this is before you get into the issues with the non trivial number of junk papers published in social science and psychology journals and the like that at best seem to say that even in cases of more difficult questions where more rigorous methods are valuable, this system of knowledge production fails a non trivial amount of the time.
