Anyone who has studied the history of science knows that scientists are not immune to the non-rational dynamics of the herd.
This week’s March for Science is odd. Marches are usually held to defend something that’s in peril. Does anyone really think big science is in danger? The mere fact that the March was scheduled for Earth Day betrays what the event is really about: politics. The organizers admitted as much early on, though they’re now busy trying to cover the event in sciencey camouflage.
If past is prologue, expect to hear a lot about the supposed “consensus” on catastrophic climate change this week. The purpose of this claim is to shut up skeptical non-scientists.
How should non-scientists respond when told about this consensus? We can’t all study climate science. But since politics often masquerades as science, we need a way to tell one from the other.
“Consensus,” according to Merriam-Webster, means both “general agreement” and “group solidarity in sentiment and belief.” That sums up the problem. Is this consensus based on solid evidence and sound logic, or social pressure and groupthink?
When can you doubt a consensus? Your best bet is to look at the process that produced, defends and transmits the supposed consensus.
Anyone who has studied the history of science knows that scientists are prone to herd instincts. Many false ideas once enjoyed consensus. Indeed, the “power of the paradigm” often blinds scientists to alternatives to their view. Question the paradigm, and some respond with anger.
