Galton's On The Origin Of Species

Decent Essays
The poster being critiqued uses a ‘family tree’ theme to convey the theory of heritability of intelligence. The theme logically fits the theory and, to some extent, is memorable. However, there is arguably too much text for the poster to be understood in a few minutes. The poster also includes information about environmental factors that influence intelligence, potentially distracting the viewer from the main concept of heritability. A solution to these critiques is to focus solely on the theory of heritability, thus minimising text and preventing confusion.
The theory of heritability of intelligence was proposed by Francis Galton (1869) in his book ‘Hereditary Genius’; the first scientific study of ingenuity. Galton was influenced by his cousin’s (Charles Darwin, 1859) book ‘On the Origin of Species’ which portrays the thesis that animals

To tests this, he developed historiometry, defined as quantitative analysis of historical data about representative people (Simonton, 1990). Following Adolphe Quetelet’s research, one of the first to use historiometry (Simonton, 1997), Galton obtained data about imminent men from biographical sources which he compared in numerous ways. His analyses concluded that the number of imminent relatives when comparing first degree relatives to second degree and so forth, had an inverse relationship: the more distant the relative of an imminent individual, the less likely they were themselves to be imminent; Galton perceived this as evidence for heritability of intelligence. This research has limitations however, including the use of retrospective data and the difficulty in distinguishing nature and nurture. Galton, aware of these limitations, sought to compare twins, overcoming these critiques. In his paper ‘The History of Twins’ (Galton, 1876) he concluded the evidence supported nature rather than
