*sigh*If you look at things on the whole "the best" almost always costs more, no one has ever said that McDonalds produces the best food anyway (so I'm not sure where you're going with that), just that they're the most popular and that is mainly because they're cheap. We can use people as an even more salient example. Free clinics don't have doctors that are as good as an expensive private practice.
Or cars. I can get a crappy car for like $2000 or I can spend a half million and get some ultra-luxury sports car. Or houses. Or horses. Or computers.
So if psychic detectives have any merit we should see high quality among the most costly (if they can save people then their time is valuable and thus they'll be able to charge more, on the other hand if they fail especially often their time is not valuable and they can't charge much). Instead what we see is that psychics are about equally effective no matter how popular they are. Either this means that all people with psychic powers have them at almost exactly the same level or that none of them have psychic powers or that even the best powers are uselessly imprecise.
