In psychology, it’s called attitude polarization, where we ignore data that conflicts with an ideology while accepting data that confirms it. It’s a known common human bias.

Scientists train themselves to accept new data as challenging old presumptions (that maybe the old model is false, or simplistic and some unconsidered noise is affecting observed data)… at least when they’re doing real science. Failure to do so, and to cling to older models, is how old dudes get tagged as hidebound reactionaries. And even Einstein couldn’t square his feelings regarding Heisenberg probability models of quantum dynamics.
