Religion

Quite a bit, really.

The concept of genetic memory has been out of favor for a while, now, although amateurs like me still ask why babies are afraid of spiders and don't like the answers.

Nobody seems to believe in tabula rasa much any more, either, although I've come across this idea of "cognitive modules", which seems like a desperate stretch. Nativism doesn't seem much better.

I should admit my personal view of psychology as an immature science and at this point little better than religion. Not even up to the low standards of economics. (My first economics course in college began by the department head telling us everything we were about to learn was bullshit. The psych prof though, was so proud of the understandings she was about to bestow on use, even though the textbook was 10 years old)

As to black holes, this was a theoretical attempt to explain an unexplainable observation. While the technique is modern, why is it substantially different from Thor's hammer causing thunder or a geocentric universe? We answer questions within the limits of our knowledge. That's kinda where ontology and epistemology slug it out.
