A study has found that people's endorsement of moral values fluctuates seasonally, with group-focused values like loyalty, authority, and purity being more strongly supported in spring and fall. This fluctuation has significant implications for politics, legal decisions, and public health, as shifts in moral values can influence behaviors and judgments. The research also suggests a link between anxiety levels and these moral shifts, pointing to the potential impact of seasonal changes on societal outcomes.

A study reveals that Democrats and Republicans overestimate how much the opposing party approves of clearly immoral acts like theft or animal abuse. This "basic morality bias" is evident in social media posts and survey results, leading to increased political animosity.
