Wikipedia:Fear all change

There's nothing wrong with not wanting to try something a new way because you think it's a bad idea, and can easily envision specific bad things happening because of it. But too many people oppose new ideas just because they're new ideas. Because it hasn't been done that way before. Because it could potentially open a "Pandora's box". Because there was not consensus for it beforehand.

The way a meritocracy would handle this is to try the new process, see if it works better, keep it if it does, and go back to the old way if it doesn't. The way Vogons would handle this is to require a 3-part RFC beforehand, advanced permission from WMF and Jimbo, and absolute proof it will work before it's even tried out, at which time they would still oppose it just because it's a new idea.

Guess which way Wikipedia usually handles it?
