Ask for a small, genuine favor from someone you want to build rapport with
Request something real and modest — help you actually need — not a pretext.
Why it works
The Ben Franklin Effect works because doing a favor activates cognitive dissonance — "why am I helping this person?" — which the mind resolves by concluding "I must like them." This self-perception revision is automatic and operates below conscious awareness. The key is that the favor must be small enough to feel freely chosen (not coerced by status) and real enough that refusing it is awkward but not impossible.
How to do it
- Identify a specific, modest help you genuinely need: feedback on a draft, a book recommendation, advice on a decision in their area of expertise.
- Make the ask specific and bounded: not "help me with this project" but "would you read this two-page summary and tell me if the logic holds?"
- Thank them sincerely and specifically afterward — the gratitude closes the loop and validates their generosity self-attribution.
Evidence
Jecker & Landy (1969) ran an experiment in which participants who were asked to return their prize money (as a favor to the researcher) rated the researcher more favorably than those who were not asked. This is the most direct experimental confirmation of the effect. (observational)
The original study used a relatively artificial lab setup; the effect has been replicated directionally but with variation in magnitude. The mechanism (dissonance vs. self-perception) is debated but the behavioral effect is consistent.

Common mistake
Asking for a favor that is actually large enough to create resentment rather than dissonance — the effect reverses when the cost of the favor is high and the person regrets helping.

More practices for The Ben Franklin Effect, Made Practical
- Ask for their expertise or opinion — not just their help
Requesting someone’s expert opinion generates more liking than requesting their labor.
- Close the favor with specific, sincere gratitude
Specific thanks reinforces the helper’s positive self-attribution and deepens the effect.
- Build a pattern of small asks rather than one large one
Multiple small favors over time create a deeper liking pattern than a single large ask.
- Use a small ask to repair a strained relationship
In a cool or conflicted relationship, asking for a small favor can reset the dynamic more effectively than doing one.
- Keep asks sized to what the person can easily afford to give
A favor that costs the helper too much produces regret, not liking.
- Invite clients or reports to contribute insight to your approach
Asking someone you lead for their input increases their investment in the outcome.
