Illusory Correlation

Illusory Correlation is the phenomenon of perceiving a relationship between variables (typically people, events, or behaviours) even when no such relationship exists. A false association may be formed because rare or novel occurrences seem more important and therefore tend to capture one’s attention.

A useful counter-measure is to consider how likely is the data to actually be random? What supports it being correlated or not correlated? Where is the evidence of the perceived link between the variables?
