    🚨 New preprint with & Nicolas Claidière on rumor diffusion 🚨 We explain why so many rumors (like the ones below) are attributed to a credible friend of a friend. Pre-print: 1/5

    Had a great poster session at where I presented our paper on fake news: 🙃

    And the effect seems to be mainly driven by the most false statement, which is not very reassuring... (Thanks for making the data so easily available, it's fun to play with 😊)

    9/13 When comparing the trust ratings that our fictive media outlets received with the trust ratings that laypeople attribute to real mainstream media and junk media, we found that the only way to enter the mainstream media category is to share no fake news at all.

    8/13 But do these results hold for political news? Yes! The negative effect on trust of sharing one fake news story, is larger than the positive effect on trust of sharing one real news story, even when the news is politically congruent!

    7/13 This is exactly what we found! Participants decreased the trust granted to sources sharing one fake news against a background of real news more than they increased the trust granted to sources sharing one real news against a background of fake news.

    7/9 Glyphosate is an *herbicide*, not a pesticide. And all the scientific agencies that evaluated its toxicity for human health concluded that it is not dangerous at the dose we are exposed to. Why isn’t this consensus mentioned in the book?

    1/9 In her new book, Naomi Oreskes argues that the epistemic value of science lies in its social dimension and that we should promote diversity. It’s not news (Cf. Kitcher, 1993) but the point is worth making again. And yet, I stumbled on a few scientific inaccuracies...

    We believe that people coming to science festivals are good targets for science communication policies, as it is possible to leverage their trust and interest in science to spread scientific arguments outside the scope of the festivals through interpersonal communication. 8/9

    In the case of GMOs the shift was drastic: most participants came to our workshop thinking that GMOs are somewhat dangerous for human health and left thinking that GMOs were more or less harmless.

    Our intervention successfully reinforced participants’ positive opinions on vaccination:

    The science is clear: vaccination’s benefits outweigh its costs and GMOs on the market are as safe as non-GMOs. But despite the scientific consensus, public acceptance of vaccination and GM food is low and opposition is stiff. What can we do about that? 2/9

    I recently gave an introductory course in evolutionary psychology and found out that YouTube videos are an amazing support. I particularly recommend this one Students loved it and it illustrates perfectly the most important principles of natural selection.

    Steven Pinker enlightening the ENS ⁦⁩.
 Sentiment mapping shows that the use of negative words has increased in the media even though progress is being made everyday… Bad is stronger than good but Pinker believes that reason is stronger than bad.

    After explaining what is a scientific proof and arguing with 103 people (13 to 80-year-old), they were more likely to think that vaccines are beneficial (η2 = 0.06) and that GMOs are harmless to human health (η2 = 0.43).

    For the festival of science we are trying to change people’s mind on Vaccination & GMOs by explaining what is the scientific method. Results of our intervention will be known next week!
