IDEA FOUND // IDEA 14
Availability Heuristic
“If an example comes to mind quickly, must it also be common in the world?”
01 / PLAINLY
What it means, plainly
When an example is easy to recall or imagine, it can feel more common than it really is.
02 / CONTEXT
A little more
When judging frequency or probability, people often use how easily examples can be recalled or imagined. That cue can help, but recent news, vivid images, and personal experience can distort it.
03 / WHY IT MATTERS
Why it matters
It can scramble priorities, drawing attention to memorable risks while quieter but more common problems receive less notice.
04 / EXAMPLE
A familiar example
After watching several reports about stolen luggage, a traveler may overestimate that risk relative to less memorable but more common problems.
05 / LIMIT
What it does not mean
Easy recall does not by itself prove a judgment is wrong; memory sometimes does reflect a real frequency.
06 / NOTICE
Notice it in your day
Choose a risk that worries you and list the examples behind that feeling. Before estimating its frequency, look for a relevant base rate.
FINAL NOTE
The idea worth keeping
When the number matters, replace ease of recall with a relevant base rate from an appropriate source.
QUESTIONS / 02
Questions people still have
Does a vivid news story show that an event is common?
No. It explains why the event is easy to recall, but frequency still requires an appropriate base rate.
Is easy recall always a useless cue?
No. It can help when memory reflects representative experience; for an important choice, check whether that is actually true.
