While we claim to value directness, relationships are built on shared fictions and assumptions that would be destroyed by blunt honesty.

People's conscious, stated reasons for their actions (proximate explanations) often obscure deeper, unconscious evolutionary drivers (ultimate explanations), such as the drive to reduce mating competition while appearing compassionate.

Humans are heavily influenced by what others do, even when they consciously deny it. In a California study, homeowners' energy usage was most strongly predicted by their neighbors' habits. However, when surveyed, these same residents ranked social influence as the least important factor in their decisions, revealing a powerful disconnect between our perceived autonomy and actual behavior.
