I get this a bit at my job, and I think there's a difference between making changes (which I do a lot of) and being confident in the changes that you're making. The environment I'm in is completely fault-intolerant, and we're currently hamstrung by our hardware (e.g. no backups/no secondaries/etc.) so changes that we're making have to be well-reasoned and argued before they're put in.

Some people take that as being scared, but it's more like "you have to have made this work and tested it before putting it in."
