In my experience, talking to the lay public, 99.999999% of ideas they throw at you will not work for any given field of science.

With scientists/eng/doc its closer to 99% non working ideas.

Cursory glances at even ideas I come up with; typically tossing away 9/10 of what I come up with.

/edit, i am heavily biased towards ideas i come up with ;)
