What is base rate heuristic in psychology?

What are the 3 types of rates?

What is base rate in decision-making?
What are Base Rates? Base rates in decision-making explain known probabilities established from historical data. A simple example is knowing what the temperature in London in May will be. Historical data tells us the temperature ranges from 15 to 19 degrees with it becoming warmer later in the month.
What are the 3 types of heuristics psychology?

What is an example of base rate fallacy?
If you play poker and assume different odds than those that apply, you are subject to the base-rate fallacy — and likely to lose. The objective odds are the base rate. People often think the information they have is more relevant than it actually is.

Why do people ignore base rates?
Specifically, we ignore base rate information because we believe it to be irrelevant to the judgment we are making. Bar-Hillel contends that, prior to making a judgment, we categorize the information given to us into different levels of relevance.

What does heuristic mean in psychology?
Heuristics are rules-of-thumb that can be applied to guide decision-making based on a more limited subset of the available information. Because they rely on less information, heuristics are assumed to facilitate faster decision-making than strategies that require more information.
