Is absolute belief in one’s one ability to estimate how every human language could possibly work terribly scientific?

Me, I like scoping claims to what is measured.

You say that like no one's ever bothered to measure what kinds of sounds can be used in human languages.

The opposite is the case; this is not a lightly studied field.

It's scientific to say other languages are "predicted" to show similar results, but unscientific to say we know they do.
