I take it that you are aware that in addition to his major contribution
to solid state physics Fredrick Sietz was the original denier for hire
with RJ Reynolds to help them keep the suckers smoking tobacco and dying
of cancer for as long as possible. His methods still work.

He pioneered the technique of creating doubt in the public mind to
prevent them making rational decisions based on scientific evidence.

You can take anything he says with a very large pinch of salt.

Yes, there is a full account of Sietz's career as a propogandist he

But I don't suppose Herr Muehlbauer has an attention span great enough
to watch that video through to the end :-(
