Social Impact Theory Calculator (Latané)

Compute social impact from strength, immediacy and number of sources using Bibb Latané\u2019s social impact theory with diminishing returns (t = 1/2).

Strength (S) 0–10

Immediacy (I) 0–10

Number of sources (N)

Anwendungsfälle

•Teaching social psychology.
•Modelling conformity in small groups.
•Designing peer-pressure experiments.

Formel

Impact = f(S, I, N) = S × I × N^t, with t = 1/2 (a doubling of sources raises impact by √2 ≈ 1.41, not 2).

Häufig gestellte Fragen

What does "strength" mean?

Latané defined it as the importance, power, authority, or expertise of the source relative to the target. Use a 0–10 scale where 10 is a very authoritative source.

Why t = 1/2?

Empirical studies on conformity, compliance and bystander intervention showed the marginal impact of each extra source diminishes. A square-root relationship fit the data better than linear aggregation.
