A recent study shows a surge in cognitive distortions in recent decades

An interesting analysis of language use by Bollen and colleagues (2021) has shown that in recent decades there has been a ‘surge in prevalence’ of written markers of cognitive distortions (cognitive distortions are associated with depression and internalising disorders). This suggests that there has been a shift towards the types of thinking associated with such disorders.

The abstract reads:

Individuals with depression are prone to maladaptive patterns of thinking, known as cognitive distortions, whereby they think about themselves, the world, and the future in overly nega- tive and inaccurate ways. These distortions are associated with marked changes in an individual’s mood, behavior, and language. We hypothesize that societies can undergo similar changes in their collective psychology that are reflected in historical records of language use. Here, we investigate the prevalence of textual markers of cognitive distortions in over 14 million books for the past 125 y and observe a surge of their prevalence since the 1980s, to levels exceeding those of the Great Depression and both World Wars. This pattern does not seem to be driven by changes in word meaning, publishing and writing standards, or the Google Books sample. Our results suggest a recent societal shift toward language associated with cognitive distortions and internalizing disorders.
