Need-for-Cognition Targeting

What it is

Tailoring a message to how much the audience enjoys thinking — arguments and evidence for those who do, cues and slogans for those who do not, and imitation evidence for the thinkers who will not check — so that persuasion runs through whichever route the target is least likely to scrutinize.

How it works

Cacioppo and Petty introduced need for cognition in 1982 as a stable individual difference in the tendency to engage in and enjoy effortful thinking, and their 1996 review documented decades of findings: high scorers seek information, form attitudes based on argument quality, hold those attitudes more persistently, and resist counter-persuasion; low scorers rely more on source attractiveness, consensus, and the sheer number of arguments. In the elaboration likelihood model this maps onto the central and peripheral routes. The targeting logic follows. For low-need audiences, persuaders lead with likable sources, repetition, and slogans. For high-need audiences, they supply the appearance of depth — jargon, citations, charts, long-form — because high elaborators are persuaded by strong arguments but can be fooled by pseudo-arguments that pass a plausibility check they do not complete. Matz and colleagues showed in 2017 that ads matched to personality traits inferred from digital footprints modestly outperformed mismatched ones, though the effects are small and the Cambridge Analytica claims built on such work were wildly overstated. The honest use is fitting the depth of a message to its audience without changing its truth. The dishonest use is choosing the route that bypasses each audience's scrutiny.

Real-world examples

  • •Cacioppo, Petty and Morris (1983) found that participants high in need for cognition were moved by argument quality and recalled more of the message, while low-need participants were less sensitive to argument quality and more to peripheral features.
  • •Matz, Kosinski, Nave and Stillwell (2017): Facebook ads tailored to users' inferred extraversion or openness produced roughly 40 percent more clicks and 50 percent more purchases than mismatched ads — from a low base, in a study whose methods and the wider claims of psychographic targeting have since been contested.
  • •Supplement and finance marketing aimed at analytical audiences uses white papers, footnotes, and mechanism diagrams; the citations often lead to studies that do not support the claim, betting that the reader checks the presence of references rather than their content.
  • •Political campaigns run the same message in two registers — a data-heavy op-ed for high-elaboration readers and a slogan with a face for everyone else — on every side of every election since audience segmentation became routine.

Ethical guidelines

Where the line is

Adjusting the depth and format of a truthful message to the audience is ordinary good communication; it becomes manipulation when the route is chosen to evade each audience's scrutiny — cues for those who will not think, pseudo-evidence for those who will not check — or when psychological profiling is used to select messages without the audience's knowledge.

  • ●Match the depth of the message to the audience, not the truth of it; a slogan for one audience and a white paper for another must say the same thing.
  • ●Do not use the trappings of evidence — citations, charts, jargon — to satisfy a plausibility check that the underlying claim would fail.
  • ●Disclose targeting: if a message was selected because of an inferred psychological profile, the audience has a right to know.
  • ●For low-elaboration audiences, keep peripheral cues honest; a likable source is a fair cue only if the source actually endorses the claim on its merits.

How to defend against it

  • ►Know your own route. If you enjoy thinking, your vulnerability is pseudo-depth: open the citations and check that they say what the message says.
  • ►If you are tired or uninterested, your vulnerability is the cue: strip the source, the consensus, and the slogan, and ask what the claim actually is.
  • ►Count the arguments and then ignore the count; the number of points is not evidence, and low-elaboration processing treats it as if it were.
  • ►When a message seems precisely pitched to you — your vocabulary, your concerns, your aesthetic — assume you were profiled and read it as an advertisement rather than as information.
  • ►Apply the accuracy prompt: before sharing, ask yourself whether the claim is true, which shifts processing to the central route.

Vulnerable-Audience Screenminutes

Before launch, ask who will actually receive the message, which of them are least able to evaluate or resist it, and what it does to them; then change the targeting, the tactic, or the safeguards so that the campaign does not get its results from the people least able to say no.

Every playbook entry states how strong its evidence is and when not to use it. Browse the full playbook.
