Are highly reliable tests – if a person scores well on one occasion, they are highly likely to perform similarly well again. The validity could be questionable – the tests measure deductive reasoning. Spearman would argue that this is a cognitive skill which is part of ‘g’, so is a valid measure of intelligence. However, Gardner for example would argue that this is just one type of intelligence (e.g. logical-mathematical) and so the test is not validly measuring intelligence as a whole.
