Origin of the word
Although the origin of the word bias is not known for certain, it may derive from Old French in the 13th century by way of Old Provençal ‘biais’ meaning ‘at an angle or crosswise’. The Old French meaning of ‘against the grain or sideways’ is similar and the French definition was ‘a slope or slant’, which by the 1520s had become ‘a diagonal line or oblique’. In the 1560s and 1570s, the game of bowls adopted bias as a technical term to refer to balls that were weighted on one side, so that they curved when bowled. In due course, bias acquired a legal definition and came to mean ‘prejudice’. In the early 1600s, it was used in phrases such as ‘giving a bias to’ meaning ‘causing to incline to one side’.

“Other animals, such as polar bears or chimpanzees also have handedness — chimpanzees have been known to prefer one hand to the other when using tools or looking for food, but the split within a population hangs around 50/50.
