This gets a lot of play in UG and early grad methods classes but SO little attention in actual practice. I mean, we think about it, yeah, but not very rigorously.

Addressing demand artifacts in psychological research (and beyond)

Olivier Corneille @ocorneille.bsky.social · 20/08/2026
Recommendations for addressing demand artifacts have been discussed in a fragmented way, and some widely used approaches have notable limitations. In this new article, my co-authors and I provide a structured review of leading methods in the field:

Demand artifacts threaten both the internal and external validity of research. Often viewed as a "scarecrow" or a "vexing problem," they can discourage researchers from examining them too closely. Yet, our conclusion offers a more optimistic and actionable perspective on these artifacts:

In this new research, we found that truth beliefs can be successfully conditioned: Statements - true and false - are rated as more true after their pairing with positive than negative pictures. This effect bridges research on evaluative conditioning and misinformation. osf.io/preprints/ps...

Even with skin tone as a group marker and explicit instructions to form group-based impressions, people relied more on the actual characteristics of the individual they encountered.

Olivier Corneille @ocorneille.bsky.social · 14/11/2025
In this research, we found that individuating information dominates social group information when forming impressions about members of newly learned social groups. This dominance was observed both on self-reports *and* more automatic measures *despite* conditions favoring group-level impressions.

I found the general discussion rather cautious, but this point might be further elaborated on. Another issue is that these manipulations are sometimes totally ineffective (Ps simply don't trust a hypothesis that runs against commonsense) but this does not seem to apply in this case 3/

Olivier Corneille @ocorneille.bsky.social · 12/11/2025
As a result, demand effects may operate differently in these studies vs. in original procedures where the experimental hypothesis is not directly communicated. The same issue applies when probing demand effects based on instruction-based replication procedures 2/

Olivier Corneille @ocorneille.bsky.social · 12/11/2025
If I may add a few thoughts, a major issue with this widespread approach to demand effects is that experimenters usually do not tell their Ps about their hypothesis. This communication creates unique demand characteristics that may consequentially depart from the original procedure 1/
