What are some principles that people rely on when making inductive inferences?

People rely on few different things when making inductive reasoning-
Representativeness of observations: people look at how well do the observations about a particular category represent all of the members of that category.
Number of observations:the conclusion that the sun will rise tomorrow is strong as it is supported by large amount of observations (we know that the sun rises every day).
Quality of the evidence:stronger evidence=stronger concusions. For example not only concluding that the sun will rise tomorrow merely basing our assumptions on observation but adding some scientific measurements about earth rotations.

''Inductive reasoning provides the mechanism for using past experiences to guide present behaviour''. People often use shortcuts to help them reach the conclusion faster and with less effort, using heuristics for example.
The availability heuristic is related to how often we expect events to occur, whereas the representativeness heuristic is related to the idea that people often make judgements based on how much one event resembles another event.
