Once someone is mentally engaged, they continue along the path they’ve started, just to finish it.

— From Pre-Suasion by Robert Cialdini

Questions pull people into generating their own answers, and self-generated reasons feel truer than borrowed ones. They also make the listener an active partner.

Magnetizers create momentum. Once someone is mentally engaged, they continue along the path they’ve started, just to finish it. Your job is to ensure the path they’re finishing leads through your key idea, not away from it.

If attractors capture attention, magnetizers keep it. Cialdini lists the features that make focus stick: the self-relevant (again, because we never tire of ourselves), the unfinished, and the mysterious. Each exploits a small, productive discomfort — the mind dislikes a loose end and will hold attention on anything that promises to tie it off.

The engine here is the Zeigarnik effect: unresolved tasks and open questions linger in memory more insistently than completed ones. Storytellers weaponize it with cliffhangers; teachers with a puzzle posed before the answer; advertisers with a question left dangling. Cialdini recounts reorganizing his own lectures around mysteries — opening with a genuine puzzle and withholding its resolution — and finding that attention, and retention, rose because the audience was working to close the loop alongside him.

For a communicator the instruction is to build in tension rather than front-load conclusions. Lead with the unanswered question, the incomplete pattern, the 'here's the strange part,' and the audience supplies its own attention to reach resolution. Cialdini notes the honest version of this: the mystery must actually pay off. An open loop that resolves into something empty trains the audience to stop leaning in, so the magnetizer only compounds when the promised payoff is real.

Self-relevance magnetizes as well as attracts. Content that is about the audience — their situation, their name, their stake in the outcome — holds focus longer than content about the communicator, because interest in the self does not fatigue. Cialdini's practical rule collapses to a sentence: to keep attention, keep making the material about them, and let the unanswered question about their own situation do the pulling. The two families work in sequence — an attractor opens the gate and a magnetizer holds it open — so a message that only grabs attention without sustaining it wins the glance but loses the argument. The craft is to pair a strong opening cue with a genuine open loop that the message itself is built to close.
