Considering conservatism has the same problems any other terminal value, yes, absolutely.

https://en.wikipedia.org/wiki/Deutsche_Physik

Deutsche Physik (literally: "German Physics") or Aryan Physics (German: Arische Physik) was a nationalist movement in the German physics community in the early 1930s opposed to the work of Albert Einstein and other modern theoretically based physics, labeled "Jewish Physics" (German: Jüdische Physik). The term was taken from the title of a 4-volume physics textbook by Nobel Laureate Philipp Lenard in the 1930s. A pseudoscientific movement,[citation needed] it nonetheless won the support of many eminent physicists in Germany.

The overall point is that political values are terminal, if reality conflicts with your most deeply held views you will contest reality in any way possible.

You can even see it in the far left today with cries of "white science."

One of my favorite quotes:

I've never joined any organization—not even the ones I've organized myself. I prize my own independence too much. And philosophically, I could never accept any rigid dogma or ideology, whether it's Christianity or Marxism. One of the most important things in life is what Judge Learned Hand described as 'that ever-gnawing inner doubt as to whether you're right.' If you don't have that, if you think you've got an inside track to absolute truth, you become doctrinaire, humorless and intellectually constipated. The greatest crimes in history have been perpetrated by such religious and political and racial fanatics, from the persecutions of the Inquisition on down to Communist purges and Nazi genocide.
