Daniel’s Answer
Usually it boils down to money. Programs that bring in lots of cash can sustain more fully funded PhD spots. So areas where there's more grant money tend to grow their ranks off of that, instead of relying on just the University's support, which is limited at best.

I agree with Daniel's answer. Generally speaking, tech and STEM PhD programs pay you but you have to pay for humanities degrees.
If you have an interest in psychology but funding is a concern, there are psychology-adjacent PhD programs. For example, I did my PhD in Human-Computer Interaction, which is an area of computer science. My PhD was fully funded and I even got a stipend from the school. I did interviews and usability studies around educational video games and ways we can better influence positive behaviors and learning in students through play.
You do need to have some computer science background though, and I did have to take core computer science classes my first few years.
