It's an economic problem. Right now, there's this torrent of new minds to come up with new ideas thanks to their lack of preconceptions, so there's no effort put towards alternatives.

There's a lot of possibilities that will open up as our tech advances. Say, wiping all memories of your field so you can learn it again with a fresh mind. Spawning short-lived digital clones of your mind with the mental 'temperature' turned up, in whatever way that's possible- maybe just dose them up with synthetic lsd in different doses- and observe the results. Lots of ways to get novel ideas without having to rely on wastefully growing billions of brains (and the attached bodies!) before throwing them, and most of the information in them, away to rot.
