> For example, there is significant disagreement within economics on, say, minimum wage. It would be an abuse of authority for an economist (for example, Paul Krugman) to claim we ought to raise the minimum wage because there is an economic consensus that we should do so, when in fact there is not and the said economist wants to raise minimum wage because it's a progressive cause.
There is disagreement, but everything I've read has been more along the line of disagreements as to how severe the side effects were, but that they're almost exclusively weighted in favor of the upsides. Feel free to link me if you've read otherwise.
And disagreement within science is good until you can have irrefutable proof (although apparently this can still be ignored). But having policy based on science even when disputed isn't bad. You can always change it according to new results/studies.
> ...and as a progressive he clearly is under the impression that such a technocracy would come to nearly exclusively progressive conclusions. But of course this denies the fundamental truth that he could find a perfectly rational opponent for any of the causes he supports, from public funding of science to Britain's membership in the EU.
You say that, but can you though? I'm honestly considering the possibility that fact based politics has somehow been smeared as "progressive". Especially on public funding of science. That is something I can't even imagine a possible counter argument against. Sponsored science is at best extremely tricky, and most often simply tainted.
I'm not a fan of deGrasse, but in this I can't help but agree with him.
You're under the impression that him being "progressive" colors his views on science. I'm of the impression that it's the complete reversal.
