Not only is that just one possible bias, it’s a less-common bias than its opposite. Generally speaking, more people are afraid to stick their necks out and say something extreme than actively biased towards doing so. Generally speaking, being wrong feels more bad than being right feels good. There are exceptions; some people are contrarians, for example (and so it’s plausible I’m one of them) but again, talking about people in general, the bias goes in the opposite direction from what you say.
