Researchers found that smokers who try to suppress their thoughts of smoking tend to smoke more than usual when they stop, a phenomenon known as behavioral rebound. This suggests that techniques like thought suppression may not be effective in quitting smoking and could even lead to increased consumption.
A new study suggests that people with a strong fusion of identity with their group will take extreme actions to protect others within the group, but not outsiders. Researchers found that those who identified as fused were more likely to sacrifice themselves for their own group members.
Children as young as 3-4 years old use statistical information to infer the preferences of others. In experiments, they were more likely to give a toy to someone who had selected it from a container with a low proportion of that toy type. This ability is crucial for learning about others' desires and preferences.
A recent study published in Psychological Science discovered that individuals who face restrictions on emigration tend to rationalize their country's system and justify its flaws. This reaction is linked to feelings of system inescapability, particularly among those experiencing poverty.
