The twin and adoption studies to distinguish the effects of genes from the effects of environment. The new birth order book claim that first-borns tend toward achievement, middle born toward diplomacy, and later-borns toward risk taking. Paulhus & colleagues at ubc and uw found that participants nominated first-borns to be highest in conscientiousness and achievement and nominated later-borns to be most agreeable and liberal but also rebellious. These claims are virtually exaggerated as most researchers have failed to uncover strong or consistent associations btw birth order and personality. Sulloway examined the association btw birth order and attitudes toward revolutionary scientific theories.
