Ben Franklin Effect – when doing a favor makes you like someone more

Do you like someone more after doing them a favor? That’s Ben Franklin Effect – when we’ve already helped someone, we’re more likely to help them again, convincing ourselves that we like them.
Where it can show up
- Colleagues – you help a coworker once, and suddenly feel more positively toward them.
- Relationships – you do a favor for someone you were neutral about, and now they seem more likable.
- Manipulation – some people exploit this effect by asking for small favors to build your trust.
A practical countermeasure
- Notice how your attitude changes – do you genuinely like the person, or are you just justifying your actions?
- Be wary of manipulation – if someone frequently asks for small favors, it may be intentional.
- Use it to your advantage – if you want someone to warm up to you, ask them for a small favor first.
