My comment wasn’t about science but about political and moral values. I doubt that the reason people don’t change them more is cognitive decline, since it seems that slowness to change them sets in long before cognitive decline sets in.
The same comment also applies to:
“why bother truly investigating my beliefs at age 70, I’m going to die soon anyway, let me just continue with the inertia until I retire soon”
It’s not just people who are 70+ who are slow to change their moral and political views.

I don’t think this is a dominant factor, but my impression is that cognitive decline sets in very early. (e.g. reaction speed peaks in mid-20s).
There was a recent paper that challenged that view. And crystallised intelligence likely peaks later than fluid intelligence. But yeah even if it turned out to be a non-trivial factor it’s likely not a dominant one until quite late.
