Very interesting to see "Technical Analysis" in this list. I'm no expert in the field, and TA always seemed like quackery to me, but I suspect many more people believe in it than for example Cryptozoology. I personally know someone who even took a course in TA, couldn't imagine anyone taking a course in looking for Bigfoot.
Technical Analysis is a bit of a mixed bag. Some parts are fairly mainstream like saying there's a bull market in tech stocks is essentially part of it. On the other hand a lot of it is like tea leaf reading.
