   Jun 22, 2023 · Confirmation bias is the tendency of people to favor information that confirms their existing beliefs or hypotheses. Confirmation bias happens when a person gives more weight to evidence that confirms their beliefs and undervalues evidence that could disprove it.

   In essence, the formula states that the posterior odds are proportional to prior odds times the likelihood. Kahneman crystallizes two keys to disciplined Bayesian reasoning: • Anchor your judgment of the probability of an outcome on a plausible base rate. • Question the diagnosticity of your evidence. Kahneman explains it with an example:

   We can use odds to compare different probabilities, by computing what is called an odds ratio – which is exactly what it sounds like. For example, let’s say that we want to know how much the positive test increases the individual’s odds of having cancer.

   We cover the interpretation of probabilities, discrete and continuous versions of Bayes’ rule, parameter estimation, and model comparison. Using seven worked examples, we illustrate these principles and set up some of the technical background for the rest of this special issue of Psychonomic Bulletin & Review.

   What is an odds ratio?

   • An odds ratio is an example of what we will later call an effect size, which is a way of quantifying how relatively large any particular statistical effect is. A final point relates to how probabilities have been interpreted. Historically, there have been two different ways that probabilities have been interpreted.

   What is probability theory?

   • It deals with the chance (the likelihood) of an event occurring. The theory of probability began with the study of games of chance such as poker. Predictions take the form of probabilities. To predict the likelihood of an earthquake, of rain, or whether you will get an A in this course, we use probabilities.

   What does probability mean?

   • Informally, we usually think of probability as a number that describes the likelihood of some event occurring, which ranges from zero (impossibility) to one (certainty). Probability can be discussed more vaguely. Chances are low it will rain today. Given there are no clouds, chances are low it will rain today.

   What is probability theory ad hoc?

   • Probability theory allows model comparison in a wide variety of scenarios. In this example the psychometrician deals with a set of three distinct models, each of which was constructed ad hoc—custom-built to capture the psychological intuition of the researcher (and a review panel).

   What is the probability of something happening?

   • In each case, these numbers are expressing how likely that particular event is, ranging from absolutely impossible (0%) to absolutely certain (100%). When we speak of the probability of something happening, we are talking how likely it is that “thing” will happen based on the conditions present.

   What is a shorthand for probability?

   • We can also using P ( ) as shorthand for probability and we can use A as shorthand for an event: Probability is usually symbolized by the letter p. The actual probability number is usually written as a decimal, though sometimes fractions or percentages are used.

   Nov 12, 2018 · Examples of such misinterpretations include: “there is a low probability that the result was due to chance,” “there is less than a 5% chance that the null hypothesis is true,” or “there is a 95% chance of finding the same result in a replication.”
