something that's quite common these days, even among the intelligent.
the Genetic Fallacy.
for sure. we have to discriminate and make decisions about how to spend time.
however , i notice people using that excuse for avoiding addressing information that directly conflicts with or questions opinions held without further investigation.
and then making these cheap shots about a topic that's far from being adequately understood.
@holon42 Sounds like what the psych field calls an heuristic, a shortcut for thinking. Yeah, laziness, but sometimes necessary so we don't have to analyze every situation and can navigate information quickly when there's a ton of it. Natural, understandable, even useful, and completely full of traps if you rely on it without awareness of what you are doing.
