\u2022 Everything is at least a little bit heritable (that is, more closely genetically related individuals are more similar phenotypically). \u2022 Nothing is 100% heritable (even identical twins are a little different from one another on anything we can measure). \u2022 Heritability is caused by many genes of small effect (there is no “gene for” in psychology, human behavior, or indeed ANY trait that commonly varies between people). \u2022 Correlations between phenotypes are partly due to correlated genetic\/heritable influences. \u2022 Heritability increases through development (at least through middle adulthood). \u2022 Trait stability or consistency across time within an individual is due to stable genetic influences. \u2022 Even things we think of as “the environment” show non-zero heritability (example: divorce). \u2022 Correlations between phenotypes and environments are partly due to correlated genetic\/heritable influences. \u2022 Most environments are not shared between people, even siblings or twins raised together. \u2022 Abnormal is normal (influences on extremes that we label as “disorders” versus normal-range traits are not different in kind, just amount). \u2022 Interpretation of results means understanding the strengths and weaknesses of choices made in the design of a study (for example: how to measure a phenotype, how participants were selected or excluded). \u2022 Phenotypes (means, variances, and presentations) change over development – we cannot use the same measures or interpretations without knowing the developmental context.
