Previous studies have indicated that explaining a hypothetical event makes the event seem more likely through the creation of causal connections. However, such effects could arise through the use of the availability heuristic; that is, subjective likelihood is increased by an event becoming easier to imagine.<ref name="Carroll1978">{{Cite journal |last=Carroll |first=John S. |year=1978 |title=The effect of imagining an event on expectations for the event: An interpretation in terms of the availability heuristic |journal=Journal of Experimental Social Psychology |volume=14 |issue=1 |pages=88–96 |doi=10.1016/0022-1031(78)90062-8 |issn=0022-1031}}</ref>

A study done asked those participating to pick between two illnesses. Those doing the study wanted to know which disease they thought was more likely to cause death. In the study, they asked participants to choose between a stroke and asthma as to which one someone was more likely to die from. The researchers concluded that it depended on what experiences were available to them. If they knew someone or heard of someone that died from one of the diseases that is the one they perceived to be a higher risk to die from.<ref>{{Cite journal |last1=Pachur |first1=Thorsten |last2=Hertwig |first2=Ralph |last3=Steinmann |first3=Florian |date=2012 |title=How do people judge risks: Availability heuristic, affect heuristic, or both? |journal=Journal of Experimental Psychology: Applied |language=en |volume=18 |issue=3 |pages=314–330 |doi=10.1037/a0028279 |issn=1939-2192 |pmid=22564084 |hdl-access=free |hdl=11858/00-001M-0000-0024-F052-7}}</ref>
