The Louisville Twin Study is a longitudinal twin study which was started in 1957 at the University of Louisville by Frank Falkner. It started with 885 twins that were born in metropolitan Louisville, Kentucky and these were randomly selected to cover the full demographic spectrum of its population. The main phase of activity was in the first 40 years and the participants were repeatedly tested at different ages throughout that period. Hundreds of papers were then published from this data. In 2014, the data was digitised and further efforts have been made to contact and study the surviving subjects. [1] [2]

According to the Book of Judges, Deborah was a prophetess of God, the fourth Judge of pre-monarchic Israel and the only female judge mentioned in the Hebrew Bible. Many scholars contend that the phrase, "a woman of Lappidoth", as translated from biblical Hebrew in Judges 4:4 denotes her marital status as the wife of Lapidoth. Alternatively, "lappid" translates as "torch" or "lightning", therefore the phrase, "woman of Lappidoth" could be referencing Deborah as a "fiery woman." Deborah told Barak, an Israelite general from Kedesh in Naphtali, that God commanded him to lead an attack against the forces of Jabin king of Canaan and his military commander Sisera ; the entire narrative is recounted in chapter 4.

In behavioral genetics, the Scarr–Rowe effect, also known as the Scarr–Rowe hypothesis, refers to the proposed moderating effect of low socioeconomic status on the heritability of children's IQ. According to this hypothesis, lower socioeconomic status and greater exposure to social disadvantage during childhood leads to a decrease in the heritability of IQ, as compared to children raised in more advantaged environments. It is considered an example of gene–environment interaction. This hypothesized effect was first proposed by Sandra Scarr, who found support for it in a 1971 study of twins in Philadelphia, and these results were replicated by David C. Rowe in 1999. Since then, similar results have been replicated numerous times, though not all replication studies have yielded positive results. A 2015 meta-analysis found that the effect was predominant in the United States while less evident in societies with robust child welfare systems.
