Bobby Moore was sentenced to death in Texas way back in 1980 after he fatally shot a 73-year-old clerk during a Houston robbery. In 2014, a Texas court determined under current medical standards that Moore was intellectually disabled – with evidence including low IQ scores and his inability to tell the time or days of the week as a teenager. In some US states, but not all, mental disability must include an IQ value of less than 70 to avoid capital punishment. Below an IQ of 70 and you live, above 70 and you die. So in some parts of the world accurate measures of IQ can be matters of life and death. In practice in the present case, the US Supreme Court battled with the courts in Texas over the issue and Moore’s death sentence was finally changed to a life sentence in late 2019 after decades of struggle, based on Moore’s intellectual disablement.
