Prevalence-Induced Concept Change
Psychologist David Luevari and his team conducted a study on prevalence-induced concept change. They found that when we set out to reduce instances of something we deem problematic and succeed, our concept of that thing expands to include examples it previously excluded. This can create the illusion that the problem is still prevalent, masking the progress we've made. This phenomenon, called concept creep, occurs when the boundaries of concepts shift and include new phenomena that were previously not considered as examples.
