A new take on the limitations of "psychometric networks" now out in Nature Human Behavior. You don't want to put too much confidence in individual edges. Something we cautioned against in 2017.

Statistical evidence in psychological networks - Nature Human Behaviour
Psychometric network models have become increasingly popular in psychology and the social sciences. Huth et al. show that a large proportion of reported network findings are based on weak or inconclusive evidence inviting caution when interpreting results.
