"but also in some good ideas like cryonics and not in other bad ideas like extraterrestrial contact, ecological footprints, p-values, and quantum collapse,"
Your listing of 'bad' and 'good' ideas reveals more about your personal beliefs than any supposed failings of skeptics.
OK, so can you name any idea that you think is bad, is accepted/fashionable in science-oriented circles, but is rejected by skeptics for the right reasons?
I've often had half-finished LW post ideas and crossed them off for a number of reasons, mostly they were too rough or undeveloped and I didn't feel expert enough. Other people might worry their post would be judged harshly, or feel overwhelmed, or worried about topicality, or they just want some community input before adding it.
So: this is a special sort of open thread. Please post your unfinished ideas and sketches for LW posts here as comments, if you would like constructive critique, assistance and checking from people with more expertise, etc. Just pile them in without worrying too much. Ideas can be as short as a single sentence or as long as a finished post. Both subject and presentation are on topic in replies. Bad ideas should be mined for whatever good can be found in them. Good ideas should be poked with challenges to make them stronger. No being nasty!
