For example, because of massive number of films and online short videos, the population is convinced that Tesla is a great inventor. The population is more likely to give a positive opinion (or positive familiarity) on Tesla Inc, even though the greatness of an 19th inventor is unrelated with the trustworthiness of Tesla Inc.

Example 2: ZOOM technology, a company irrelevant with the online video conferencing technology, surged from 1.05 USD to 10.40 USD per share during the outbreak of Covid in early 2020. At the same time, Corona popularity also vastly increased.

What is the academic terminology or related papers on this heuristic?

Examples of similar effects include "stereotype heuristic".

    $\begingroup$ "The population is more likely to give a positive opinion on Tesla Inc" Do you have evidence for this, or this is just a hypothetical assumption? $\endgroup$

  • $\begingroup$ I think you'd have to be very careful when measuring something like this to avoid biases in the measurement itself that aren't really related to a true association as proposed. $\endgroup$

    $\begingroup$ @ArnonWeinberg Hi Arnon, the link you posted is more related with "stereotype heuristic", just like if you find one Canadian friendly, then you would possibly think that all Canadians are more likely to be friendly. In your example, both X and Y are made by A; in this question, N. Tesla has nothing to do with with Tesla Inc. I am sure that you made a good point by providing one related heuristic. $\endgroup$

    $\begingroup$ Makes sense @HighGPA, not sure if there is a separate term for this variety though. I heard that sales of Corona beer went up during the pandemic, despite the negative association, so the effect may not be robust. Also, the Halo Effect is an example of cognitive fluency, where effects like this are often demonstrated in experiments. $\endgroup$
