💡 This research highlights the impact of misinformation on health behaviors in oncology.
Next step: testing these effects in a clinical population as part of the COMBREAST project (funded by the Canceropôle Nord-Ouest) with @leotoussard.bsky.social as a postdoc researcher.

Study 3:
We tested a brief intervention inspired by the toolbox from
@anaskozyreva.bsky.social:
🔸 A combination of warnings and accuracy prompts.
👉 Result: This approach reduced conspiracy beliefs about chemotherapy and affected the intention to use conventional treatments.

➡️ An interaction was observed between exposure to the material and the perceived credibility of the article.
But what happens when credibility is experimentally manipulated?

Study 2:
A fictitious scandal, directly linked to chemotherapy this time, successfully:
✔️ Manipulated conspiracy beliefs about these treatments.
✔️ Modulated intentions to use oncological treatments.

Results from Study 1:
The scandal unrelated to chemotherapy failed to increase mistrust toward these treatments.
❓ Was it due to a lack of coherence between the article and chemotherapy?
❓ Or the article’s lack of credibility?
The next studies provided some answers.

Studies 1 & 2:
➡️ We attempted to manipulate conspiracy beliefs about chemotherapy using two types of health scandals:
A real scandal, unrelated to cancer.
A fictitious scandal, related to cancer (inspired by
@fabiovelo.bsky.social).

🔎 We conducted 3 studies to test the effects of conspiracy beliefs fueled by online misinformation on intentions to use both conventional and non-conventional treatments.
