Concepts (page 56)
- Publication Bias
Studies that find something get published. Studies that find nothing sit in a drawer. The published literature on any question is therefore a biased sample of the research actually carried out, and…
- Purchase Involvement
How much concern a person brings to a particular buying episode once the purchase has been triggered.
- Quasi-Experiment
A quasi-experiment exploits a real-world change that nobody arranged for research purposes, such as a company rolling a product out in one place before another, to approximate random assignment…
- Question Every Requirement
Question every requirement is the first step of the Algorithm, the five-step operating sequence in Jon McNeill's book of that name: treat every requirement as a claim somebody made rather than a…
- Race to the Bottom
A race to the bottom is what happens when attention merchants compete for the same limited pool of attention: content drifts toward whatever most reliably seizes it by reflex, the garish, the…

- Randomised Controlled Trial

- Rational Inattention
People economise on what they bother to work out. A heuristic that is right most of the time gets kept, which means it is a heuristic you will not notice failing.
- Reactance
Reactance is the resistance people show the moment they sense a choice is being taken from them, and it is why a reward or a nudge that feels imposed can produce less compliance rather than more…
- Reactive Hypoglycaemia
Reactive hypoglycaemia is a clinical condition in which blood sugar genuinely falls below the normal range in the hours after a meal, with symptoms to match. It is uncommon in people who do not have…
- Ready-to-Resume Plan
A ready-to-resume plan is a brief reflection on, and plan for, returning to a task you are being pulled away from. Sophie Leroy and Theresa Glomb tested it in four studies reported in Organization…
