Key takeaways
  • Contrary to what one might think, scientists don’t necessarily fit into the elitist image that we may have of them and therefore is not responsible for the mistrust.
  • Rather suspicion around science is in more likely fuelled by other perceptions of science, reinforced by the health crisis.
  • Scientists' role in the implementation of measures to combat the coronavirus has exacerbated the criticism directed at it as an institution, by consolidating science with a political function.
  • There is also confusion in the media created by “science experts” giving their opinion on issues that do not necessarily fall within their field of expertise, which undermines the credibility of the scientific community and its image.

There are count­less pro­grams, sym­po­siums or articles dedi­ca­ted to an alle­ged rise of sus­pi­cion towards science. What is your view ?

It is indeed a frequent theme. Howe­ver, opi­nion polls show a more nuan­ced rea­li­ty. When the ques­tion is more gene­ric (“Do you trust resear­chers from public ins­ti­tu­tions to tell the truth about their research topics ?”), two thirds of respon­dents ans­wer ‘yes’. Even though, in some cases, the out­look can be much dar­ker – par­ti­cu­lar­ly with regards to medi­cal topics1. Yet, the fact remains that, in gene­ral, there is more confi­dence in science than in poli­ti­cians. I do not think howe­ver that there is a fee­ling of mis­trust towards science across the board, so we need to exa­mine each case carefully. 

Tell us more !

I see two pro­blems lin­ked to the issue of mistrust. 

The first is that it is a vague notion. We some­times dis­tin­guish ‘mis­trust’, a dif­fuse fee­ling, from ‘sus­pi­cion’, a struc­tu­red atti­tude based on either good or bad rea­sons. The rea­sons for which should be inves­ti­ga­ted because there are other close notions with dif­ferent impli­ca­tions ; ‘hesi­ta­tion’, for example. It is wide­ly stu­died in regard to vac­cines, but it is not the same as mis­trust or sus­pi­cion. I also think about ‘confu­sion’, which can have the same effects as sus­pi­cion, in terms of dis­mis­sal. Howe­ver, it reflects the absence of reliable points of refe­rence, or the dif­fi­cul­ty to dif­fe­ren­tiate see­min­gly close rea­li­ties. In the lat­ter situa­tion, the caco­pho­ny bet­ween the exper­tise of agen­cies and experts on TV shows for example has crea­ted a great deal of confu­sion. In a much broa­der sense, it is at the heart of the “info­de­mic” concept revi­ved by the World Health Orga­ni­sa­tion (WHO) since Februa­ry 2020. 

A dis­tinc­tion is some­times made bet­ween dis­trust, which is a dif­fuse atti­tude, and mis­trust, which is an atti­tude struc­tu­red by reasons.

The second pro­blem is that objec­ti­fying this defiance, if it exists, and taking it for gran­ted a lit­tle too fast, can have an effect on the demo­cra­tic debate. What is the use of trying to convince people of the vali­di­ty of a mea­sure if a large part of the popu­la­tion is consi­de­red to be oppo­sed to it as a mat­ter of prin­ciple ? Last autumn, there was much talk about an impor­tant and rela­ti­ve­ly recent form of mis­trust from French people towards vac­cines. Even though at the time no Covid-19 vac­cine was avai­lable yet, which made any decla­ra­tion high­ly abs­tract. In addi­tion, the begin­ning of the Covid-19 vac­ci­na­tion cam­pai­gn sho­wed a wides­pread desire to have access to vac­ci­na­tion as soon as pos­sible (the hesi­ta­tion towards the Astra­Ze­ne­ca vac­cine being a sepa­rate case). In this par­ti­cu­lar case, the beha­viou­ral cri­te­rion – how will people concer­ned behave ? – seems more rele­vant to me than statements.

Some resear­chers speak of com­mu­ni­ty phe­no­me­na. In other words, where scien­tists form part of an elite. As such, the wor­king class can’t iden­ti­fy with them lea­ding to mis­trust towards them.  What is your opinion ? 

It should be cla­ri­fied what is meant by “elite” here. Need­less to say, the dai­ly life of resear­chers is rather dif­ferent than the life­style of busi­ness elites. Except in some par­ti­cu­lar cases, they are also deta­ched from poli­ti­cal deci­sion-making : resear­chers and engi­neers are far from over-repre­sen­ted among poli­ti­cal repre­sen­ta­tives and senators. 

It seems to me that the pro­blem is ins­tead lin­ked to how we per­ceive science. It cor­res­ponds to at least three rea­li­ties. First, there is our know­ledge of research, its condi­tions, what it’s like to be a resear­cher. This usual­ly sparks inter­est, and some confe­rences, like the Science Fes­ti­val (Fête de la science), or well-made popu­la­ri­sa­tion videos, win over a wide audience. 

Second, there is the indi­vi­dual or col­lec­tive exper­tise, within an agen­cy, a com­mis­sion, an orga­ni­sa­tion, which is often misun­ders­tood. Yet, gene­ral­ly it is a pro­ce­dure that obeys very strict rules, can lead to balan­ced judg­ment, and even some­times includes a plu­ra­li­ty of views. It col­lides with the image of ‘experts’ seen on news chan­nels, or even more gene­ral­ly, with the media image of those who feel entit­led to give their opi­nion on other scien­ti­fic dis­ci­plines or issues just because they are qua­li­fied in a par­ti­cu­lar field. This image of experts ‘in science’ does a lot of damage, and we have seen the emer­gence of many impro­vi­sed epi­de­mio­lo­gists these past few months !

Final­ly, there is the case when science is used to jus­ti­fy a poli­ti­cal deci­sion (“we fol­low science”, “science says…”). Cri­ti­cism some­times falls on science when it is in fact rai­sed against poli­tics. This last type of vision seems to fall under what we once cal­led “the linear model”. Basi­cal­ly, only one poli­cy stems from scien­ti­fic conclu­sions, yet this is illu­so­ry. Even on sub­jects that are per­fect­ly stable from the scien­ti­fic point of view, whe­ther in the field of ener­gy, health or the envi­ron­ment, there is gene­ral­ly a plu­ra­li­ty of sce­na­rios. Deci­sion-makers can­not hide behind resear­chers or experts, but they can unfor­tu­na­te­ly ignore them.

It is com­mon that conspi­ra­cy theo­ries have no scien­ti­fic basis. Could their alle­ged increase be a sign of the gro­wing mis­trust in science ?

There is indeed cause for concern. For example, the docu­men­ta­ry Hold up, which was vie­wed mil­lions of times, mixes ques­tions on the SARS-CoV‑2 virus with spe­cu­la­tion on the rea­li­ty of the out­break, the glo­bal pro­ject named “the great reset”, not to men­tion 5G, and this can have a health impact. It is pos­sible that social net­works increase the visi­bi­li­ty of this phe­no­me­non. But, even when a conspi­ra­cy theo­ry appears on a sub­ject cove­red by scien­ti­fic research as well, it is only part of the phe­no­me­non. For ins­tance, many of Donald Trump’s voters are still convin­ced that the result of the last elec­tion was a plot of the Democrats. 

Even if there is a resur­gence of conspi­ra­cy theo­ries… they do not, or hard­ly ever, tar­get research as such.

It seems to me that this last conspi­ra­cy theo­ry has severe conse­quences, and it gives no sta­te­ment on science. If we use the lan­guage of sus­pi­cion, such an atti­tude reflects a lack of trust in ins­ti­tu­tions, sus­pec­ted of fol­lo­wing a secret agen­da. Conspi­ra­cy theo­ries on scien­ti­fic sub­jects are pro­ba­bly only one aspect of this gene­ral atti­tude, only in this case they tar­get the par­ti­cu­lar ins­ti­tu­tion that is science. Per­haps it is more stri­king because the idea that a scien­ti­fic sta­te­ment could be the result of a hid­den agen­da conflicts with the values of uni­ver­sa­li­ty, truth and inte­gri­ty pre­sup­po­sed by science. Howe­ver, if you look in detail, to my know­ledge, exis­ting conspi­ra­cy theo­ries focus more on the second and third images of science men­tio­ned ear­lier. We hard­ly see any conspi­ra­cy theo­ries on black mat­ter or string theo­ry, for example. All this would sug­gest that even if there is an increase in conspi­ra­cy theo­ries, and even if we are right­ful­ly concer­ned about some of their mani­fes­ta­tions and we must address them when know­ledge is threa­te­ned, they do not neces­sa­ri­ly express defiance towards science nor tar­get research itself.
