"The phenomenon of illusory correlation is explained as an availability bias....A person is said to employ the availability heuristic whenever he estimates frequency or probability by the ease with which instances or associations could be brought to mind."
"The Illusory Correlation is sort of a combination of the Availability Heuristic and Confirmation Bias. You can easily recall the one instance when something happened (Availability Heuristic), which makes you think it happens often. Then, when it happens again – like the next full moon, for example – your Confirmation Bias kicks in and confirms your previous belief."
