It's a lot worse than it seems.
Many politicians hold scientific inquiry in complete contempt.
Randall Paul has been railing against funding for science for a very long time.
He is one of those people that mocks grants selected by rigorous peer-review at every opportunity.
I suspect this animus towards actual scientists stems from his peculiar behaviour when he abandoned the American board of ophthalmology because he disagreed with them.
Perhaps his open contempt for all things science and his cloying need to justify it constantly explains his self-destructive attitude towards vaccines.
Roughly a quarter of Americans believe that science is bad and not in the public interest (Pew).
Conservative party politicians sing to this choir.
I clicked on the link to Pew. This could lead to a very extended and I think interesting discussion, probably worth a thread of its own. Let me take just one simple result of their poll:
https://www.pewresea...up_05.png?w=620
If I understand it correctly, people were asked to choose between exactly two statements:
A: Scientists should stick to establishing sound scientific facts when it comes to policy debates about scientific issues.
B: Scientists should take an active role when it comes to policy debates about scientific issues.
Which do I choose? For B, I would like to know what sort of "active role" is envisioned. A friend once gave a math lecture wearing a T-shirt that said "P=NP? I don't know and I don't care".
If called before the Senate to testify, he could probably do pretty good job of explaining the issue and report on the progress, especially on the lack of progress. He could probably do this so that at least some of the senators would have a decent understanding of the issue. But then it should probably stop there. Here is an actual example of what I am talking about: At a recent family Christmas gathering, yes, a small gathering where we kept our distance, somehow the discussion veered into technical issues of mathematics, computer science and logic. (Yeah, Merry Christmas).. Not everyone was following the discussion about provable versus true, so I ventured in with the 3x+1 problem. It goes like this:
You start with a positive whole number x and apply a rule. The rule takes into account whether x is odd or even.
If x is od, you multiply by 3 and add 1. So 11->34
If x is even, you divide by 2. So 34->17.
Now apply this rule repeatedly and see what happens. 11->34 -> 17 -> 52 -> 26 -> 13 -> 40 -> 20 -> 10 -> 5 -> 16 -> 8 -> 4-> 2 ->1 -> 4->2 -> 1 etc
Question: Is it true that no matter which positive integer you begin with you always get to 1?
Suppose you try it for all numbers less than 100000000 and you always end up at 1. Great, but there are many numbers bigger than
100000000 so we are not done.
Suppose you try it on some number no one has ever tried before. You set the computer to work and after three days of working day and night the computer is still chugging along, not yet having reached 1. Patience, Give it time.
In neither case have we found an answer that we can prove is correct.
I am pleased to say that my granddaughter, who had been quiet for a while, said "That's the first thing anyone has said about this that I can understand."
So: If playing an active role in the debate means helping policymakers understand what has and what has not been established and with what degree f confidence, then I am all for scientists taking an active role in a policy debate. If, otoh, it means the scientist says "I know everything, shut up, listen to me, do what I say" then I am less enthusiastic.
Btw: Yes, one thing that could someday occur in the 3x+1 problem is that a cycle other than 1 -> 4->2 -> 1
is found. Say three numbers x, y, z such that x->y ->z ->x (well, it would be longer than three numbers x,y,z) and then just continues on in this cycle. This would prove that starting with that x you never get to 1. So the problem has been refined to 'Do you always reach a cycle? 1 starts a cycle 1 ->4 -> 2->1 , but there might be others. No one knows. It is either true or false that you always reach a cycle, but possibly there will never be, and never can be, a proof of which it is.
Scientists might lie, anyone might, but very few scientists do, it goes deeply against the grain. But convincing themselves that they know more than they do? We are all in danger of that.
