Why are filler words bad? Why do we need to be trained not to use them?

People in this thread point out that filler words make communication less effective, primarily by being distracting.

if you've got nothing to say, you're just adding noise.

Why do we care that much about the SNR of spoken words? Language is inherently quite redundant.

		Redundancy is still "signal" I don't think it's an argument of efficiency but rather the avoidance of noise. The "ums" isn't redundant, it's not repeating or decorating the conversation. It's filler like static. Stops people from filling the gaps with their own thoughts
