The Strange Factors That Influence What You Buy & The Fascinating Story of Data

Halo Effect

The halo effect is a powerful psychological bias where a standout characteristic of a product or person influences perceptions of other attributes. Richard Shotton explains that if a brand can project a strong positive trait, like humor or likability, it can subtly influence consumers' perceptions of trustworthiness or value 1. This effect extends beyond marketing, affecting how we judge people in everyday interactions.

If you are phenomenally friendly, and that's the thing that we notice about you when we first meet you, the halo effect suggests that we'll also assume that you are kinder, that you are more ethical, that you're more intelligent.

Mike Carruthers adds that relying solely on consumer surveys can be misleading, as people often lack introspective insight into their own motivations 1. Instead, businesses should use controlled experiments to uncover genuine drivers of behavior.

   

Effort & Value

Effort plays a crucial role in how consumers value products. Richard Shotton recounts the story of Betty Crocker's instant cake mix, which initially failed until an extra step—adding an egg—was introduced, making consumers feel more involved in the baking process 2. This principle was later confirmed by studies showing that people are willing to pay more for products they have to assemble themselves, like Ikea furniture 3.

The more effort people put into a product, the more they value it.

This insight offers marketers an opportunity to enhance product value by incorporating elements that require consumer effort.

   

Framing Effects

Framing effects demonstrate how the presentation and description of a product can alter consumer perception and behavior. Richard Shotton illustrates this with a study where the same price presented differently—$30 a month versus $1 a day—significantly changed consumer behavior 4. He also discusses how language can shape our responses, such as describing meat as 75% lean rather than 25% fat 4.

The words that are used to describe an event act as a lens, and that changes how we respond to the situation.

Mike Carruthers adds that even subtle changes in wording can manipulate consumer perceptions of value and quality 5.

   

Pratfall Effect

The pratfall effect reveals that showing vulnerability or flaws can increase a product's or person's appeal. Richard Shotton shares a study where a quiz contestant who spilled coffee on himself was rated more likable than one who didn't 6. This effect is used by brands like Guinness and Listerine to highlight minor flaws, making their strengths more believable.

The brilliant thing about admitting a flaw is you have plausibly demonstrated your honesty and therefore any other claim you make afterwards is that bit more believable.

--- Richard Shotton

This tactic helps brands stand out and build trust by appearing more authentic and relatable.
