Misdiagnosis

 Last week, the New York Times published the transcript of an interview with the the heading "Jay Bhattacharya, the N. I. H. Director, says authorities broke the public’s trust in the Covid era. Now it’s up to outsiders to restore it."  In the course of the interview, Bhattacharya said "a Pew poll in 2024 that said 25 percent of Americans don’t believe that scientists have the best interest of the public at heart. One in four. And then people will come back to me — scientists — and say, 'Well, look, 75 percent trust us.'  That’s too low a bar, Ross [the interviewer was Ross Douthat]. It needs to be 100 percent. . . . If only 75 percent of the public thinks that the work that the N.I.H. does benefits them, it’s an utter failure."  

His memory was accurate:  the survey asked "How much confidence, if any, do you have in each of the following to act in the best interests of the public? A great deal, a fair amount, not too much, no confidence at all"  For "scientists," it was 26%, 51%, 19% ,4%; for "medical scientists" it was 30%, 48%, 18%, and 4%.  How does that compare to other groups?  To make the comparison easier, I'll combine the first two categories:

The military                       78%
Medical scientists              78%
Scientists                           77%
Police officers                    73%
Public school principals    72%
Religious leaders               55%
Journalists                          45%
Business leaders                40%
Elected officials                 33%

2024 wasn't the only time that the question was asked--it was also asked a number of times beginning in 2016 and again in 2024.  The figure shows the average for four groups with relatively high confidence:  medical scientists, military, police, and principals.*

All of them followed a similar course, with a drop from 2020 to 2021, and stability since then.  You could say that trust in medical science declined "in the Covid era," but it didn't happen until vaccines were available and things were opening up (the 2020 survey was in November and the 2021 survey was in December).  That is, the "lockdowns"** and closures than Bhattacharya criticizes didn't damage public confidence in medical science:  it was higher in November 2020 than it had been in January 2019.  

The Pew report on the 2025 survey gives a breakdown of confidence in medical scientists by partisanship.  Among Democrats, it's stayed about the same; among Republicans, it dropped between 2020 and 2021 and has not recovered--not even in 2025.  Later in the interview, Bhattacharya unwittingly explains why Republican confidence didn't increase once Trump was back in office.  Douthat says that RFK Jr is "comfortable saying something positive about some vaccines, but he’s not a salesman for vaccines."  Bhattacharya replies "I think we’ve had enough of salesmen. . . .  if I had the choice between someone like the former head of H.H.S., who was not a doctor either and was much more in this politician salesman mode, or Bobby, I think Bobby will ultimately be better for American public health."  Republican confidence in medical scientists has fallen because leading Republican politicians, especially Trump, have been "salesmen" for suspicion of vaccines and medical authorities in general.  If they now turned and said that the vaccines recommended by their team of experts was really essential, Republican confidence might rebound.  But if it's just Dr Bhattacharya saying that "world public health agrees with this,"  he's appealing to the same sentiment (trust in medical experts) that Republican leaders have undermined.  

*Confidence in "scientists" was very similar to confidence in "medical scientists," so I omit it to make the figure more readable.

**The measures in the United States didn't meet the dictionary definition of  "lockdown," but that's the word he uses.
