Noel in a previous post you referred to SAGE as professional epidemiologists.
The most represented qualification on SAGE is that of mathematician. Perhaps that explains their over-reliance on modelling.
Virologists, epidemiologists and immunologists are thin on the ground.

Google a few - you'll see.
They also have sub groups feeding in to them, such as SPI-B and has 42 members. It specialises in Behavioural Science.
A previous recommendation from them to SAGE was "The perceived level of personal threat needs to be increased among those who are complacent, using hard-hitting emotional messaging."
I don't think they got it wrong through incompetence. I think it was intent. Whether that intent was to coerce, to threaten, to heighten fear... I don't know, but I think it's backfiring. They could do that in the Spring, but people aren't having it now.
I am tending to think there are other motivations though.
