The identical twins I know are very similar to each other. Just my two cents of a data point.

- tokenadult 17y agoI have nieces who are identical twins (they were tested for monozygosity after being born). But they are not even identical in appearance--I'm decent at telling them apart, and their mom does that very well. Professional geneticists are aware of cases of monozygotic twins being quite discordant in height, IQ, or various other phenotypical characteristics of interest. Some of those cases are reported in detail in the better textbooks on human genetics.

- tokenadult 17y agoHow would confirmation bias tend to run on this issue?
- byrneseyeview 17y agoDepends on how many people grew up watching Sesame Street and listening to NPR, compared to how many people grew up watching... uh... all those mainstream media sources that take the yes-there-is-human-biodiversity side of the human biodiversity debate.
- tokenadult 17y agoI referred to professional geneticists, persons who enter a graduate program of study of genetics and gain a Ph.D. and academic position in that discipline. From above: Professional geneticists are aware of cases of monozygotic twins being quite discordant in height, IQ, or various other phenotypical characteristics of interest. Some of those cases are reported in detail in the better textbooks on human genetics.
