A similar table for bits: https://gist.github.com/2415775

Good one.

I chose the decibel scale instead of using bits because bits were a bit awkward when the probabilities were close to 50%. From 0 bits to 1 the probability jumps 16.666%, and the odds doubles, but with decibels the first jump is about 6%, and doubles the odds around 3 decibels, and multiplies them by 10 in exactly 10 decibels.

Yes, decibels are easier for humans.

I'm pretty sure I'm human, but I like bits better because they have a natural interpretation as the number of answers you've received to well crafted yes/no questions, which is something that a 10 year old can understand pretty easily.

I meant the math is easier. The same reason you multiply the log by 10 when using decibels - that way, you can talk about 11 decibels instead of 1.1, which would confuse and frighten people.
