The Third-Person Effect

“A persuasive message may look dangerous for others and nearly harmless to you.”

01 / PLAINLY

What it means, plainly

The third-person hypothesis studies the tendency to believe that a message affects other people more than oneself.

02 / CONTEXT

A little more

The third-person hypothesis studies a tendency to estimate larger media effects on other people than on oneself. The gap changes with desirability, social distance, message, and measurement.

03 / WHY IT MATTERS

Why it matters

That perceived gap may support decisions about messages without equal evidence for others' vulnerability and one's own resistance.

04 / EXAMPLE

A familiar example

Someone supports banning an advertisement because it will manipulate the public while considering themselves immune.

05 / LIMIT

What it does not mean

A perceived gap proves neither personal immunity nor an actual effect on the imagined third parties.

06 / NOTICE

Notice it in your day

For a persuasive advertisement, estimate its effect on you and on another group. Write the evidence you would require for both estimates using the same standard.

FINAL NOTE

The idea worth keeping

Demand symmetrical evidence before assuming other people's vulnerability and your own resistance.

QUESTIONS / 02

Questions people still have
