(Kahneman & Tversky, 1972).
Local representativeness is
samples are perceived to represent their population to the same extent as large samples
(Tversky and Kahneman, 1971). A small sample which appears randomly distributed would reinforce the belief, under the assumption of local representativeness, that the population is randomly distributed. Conversely, a small sample with a skewed distribution would weaken this belief. If a coin toss is repeated several times and the majority of the results consists of 'heads', the assumption of local representativeness will cause the observer to believe the coin is biased toward 'heads'.
