Inside Influence Part 2: How Cialdini’s Principles of Social Proof, Scarcity, and Authority Shape Consumer Behavior

Charles Spence's book Gastrophysics argues that taste is built by every sense, not just the tongue. MichaelAaron and Richard work through the evidence: classical music lifting restaurant spend 10%, heavy cutlery raising willingness to pay 16%, rounder chocolate read as 50% creamier, and what brands should do with it.

Guinness made you wait, Avis was second, VW was small. Andy Nairn and Richard unpack why owning a flaw beats hiding one, and how the same instinct led Lucky Generals to raise its own size in pitches before a prospect could ever hold it against them. 

MichaelAaron and Richard explore why charity donations are especially resistant to typical marketing tactics. They unpack behavioral studies on anchoring, present preference bias, reciprocity, and overhead aversion that show small shifts in framing and timing can raise donations by double digits.

Courage strategist Rami Dudin joins MichaelAaron and Richard to discuss why distinctive often beats different, using SickKids' $1.3 billion fundraising turnaround, CIBC's no-fee campaign, and neobank scarcity tactics like Monzo's golden ticket to show why owning one idea can perform better than chasing novelty.

MichaelAaron and Richard explore why half of chronic-illness patients skip their medication, and why scaring them into compliance backfires. They cover a study on avoiding bad medical news, a simple diagram that cut medication errors in half, and two studies showing doctors are swayed by menu order and time of day when prescribing.

Harvard professor Michael Norton, author of The Ritual Effect, joins MichaelAaron and Richard to explore why identical actions feel meaningful to one person and trivial to another. They cover how Oreo, Stella Artois, and Guinness turn consumption into ritual, and what marketers should watch for when customers improvise their own rituals.

MichaelAaron and Richard unpack a new Behavioral Insights Team report on why most companies fail to get employees using AI, covering how social proof lifts adoption, why removing small points of friction beats motivational pitches, and why framing AI as something to lose outperforms framing it as a gain.
