N the late 1990s, several studies claimed there was a direct link between growing rates of autism and the presence of low doses of mercury used to preserve infant immunizations. In 2000, the FDA replaced all preservatives in infant inoculations with a recently developed non-mercury–based preservative that was cheaper and more efficient. Some theories stated that the government was engaged in a cover-up because it knew that mercury-based immunizations given during infancy increased the chances of young children developing autism. What is this conclusion most likely an example of?

A false association may be formed because rare or novel occurrences are more salient and therefore tend to capture one's attention.This phenomenon is one way stereotypes form and endure.

As given in the question the indication of the link is made on the basis of the perception of the relationship between the mercury based immunization and young children developing autism is the example of illusory correlation.
