It's more cost effective if things work for everyone, but it's not like we reject things because they are not generic enough. See how many different statins you can be on for example if one doesn't work for you. If RNA testing was cheaper we could skip the guessing part (for statins) though and know which one to start with. Same with different techniques in psychology.

I don't think any serious professional disagrees with different needs.
