This idea, also known as the availability bias, was first introduced by psychologists Amos Tversky and Daniel Kahneman in the 1970s. They observed that people tend to rely on immediate examples or information that comes readily to mind when making judgments or decisions.
The bias suggests that individuals often overestimate the likelihood of events or situations based on how easily they can recall relevant instances. Essentially, if we can remember it, we tend to consider it to be more important.
A classic example of availability bias can be found when people overestimate the likelihood of plane crashes compared to car accidents. This happens because plane crashes often receive tons of media coverage and we tend to remember these horrific events more vividly, even though statistically speaking, car accidents are far more common.
🎯 Here are some key takeaways:
Recognize the influence of bias
Understand that your judgments and decisions can be swayed by the ease with which examples or information come to mind.
Seek diverse perspectives
Actively gather a variety of user feedback and data sources to ensure a balanced understanding of the problem you're trying to solve.
Conduct thorough research
Look beyond immediate anecdotes and focus on comprehensive research. Try to incorporate quantitative and qualitative research using a meaningful data set.
Challenge assumptions
Question the salience and representativeness of the information at hand. Are you basing your decisions on a few memorable instances or a broader, more accurate dataset?
Don’t focus on extremes
Extremes may be memorable, but they are likely rare. Accounting for edge cases is important, but remember that this is probably not the norm, so use your time spent dealing with these cases wisely.
