Follow through on micro-commitments

Always do the small thing you said you’d do — weak ties live or die on reliability.

Why it works

Weak ties lack the forgiveness buffer of close friendships: a close friend overlooks a dropped commitment; an acquaintance simply stops investing. Consistent follow-through on small promises — sending the article, making the introduction, responding promptly — signals competence and trustworthiness, which are the qualities an acquaintance needs to confidently refer or recommend you.

How to do it

1. After any networking conversation, identify the one specific thing you committed to and note it immediately.
2. Do it within 24 hours or set a calendar reminder for the stated date.
3. If circumstances change, communicate proactively rather than silently dropping it.
4. Keep your commitments smaller than your capacity — under-promise with acquaintances so you can reliably over-deliver.

Evidence

Trust in weak ties is primarily competence-based rather than affective; perceived reliability predicts referral behaviour in professional networks. This is a mechanistic inference from trust research rather than a directly tested networking protocol. (mechanistic)

The specific threshold of follow-through needed to maintain a weak tie has not been formally studied; the mechanism draws on trust theory.

Common mistake

Treating networking conversations as socially complete in themselves and forgetting that the value is created by what happens after — the follow-through.
