I think the great stagnation is widely considered to have taken hold in the mid 70s. Institutionalisation of science has been going on since the 30s at least, if not earlier. It provided inventions massively increasing total factor productivity well into the period of institutionalisation. I think it is much more likely that whatever "disease" is causing the great stagnation is also affecting science.
