Lastly, we show that the commonly used factor structure of mental health (elifesciences.org/articles/11305) is largely shaped by these two surface-level properties. [11/14]

We provide direct evidence for these two effects in a new experiment, and use simulations to show that our findings cannot be explained by statistical artefacts. [10/14]

We then show that inattentive responders tend to be highly confident in their decisions (we have some ideas for why). Together, items that are rarely endorsed (therefore highly skewed) are more positively correlated with decision confidence. [9/14]

And second, we build on Sam Zorowitz’s work (www.nature.com/articles/s41...) and show that, indeed, inattentive responders appear highly symptomatic in items that are rarely endorsed (like item OCI-R 16) [8/14]

In line with this surface-level account, we find that, in two published datasets, correlations between poor mental health and confidence are positive for standard items (where a high rating = poor mental health), but negative for reversed items (where a low rating = poor mental health). [7/14]

First, a tendency to give high or low ratings to self-report items translates to confidence ratings. Here is a correlation between endorsement of OCI-R item 16 and participants’ general tendency to give high ratings to neutral items such as “there are relatively few breeds of cats”: [6/14]

We think we now understand what is going on. We show that correlations of confidence with mental health in online studies are largely driven by two surface-level properties of questionnaire-filling behaviour: rating biases and inattentive responding. [5/14]

In recent studies, it has been found that endorsement of this item (and other items that measure compulsivity) is associated with high levels of confidence in perceptual decision-making tasks. We replicated this finding. [3/14]

Take a moment to read this item: “I feel that there are good and bad numbers”. This is item number 16 from the OCI-R questionnaire: a list of 18 questions that is used to assess obsessive-compulsive tendencies. [2/14]
