# Chapter 5. Feeling, Prediction and the Body

Examines the evidence on faces, bodily signals and social emotions, defines the predictive term "precision", and proposes one narrow experiment a predictive account of feeling could fail.

The chapter begins with Darwin's 1872 argument that the main emotional expressions are inherited and common to all people, and with Paul Ekman's later programme of six or seven basic emotions, each supposedly carrying its own face and physiology. That list has been heavily qualified, though not abandoned. A 2019 review judged facial movements to be weak and unspecific signs of emotion categories, studies with Himba herders and Trobriand adolescents did not reproduce the expected groupings, and a meta-analysis of 202 studies found no distinct bodily pattern for each emotion. Rival studies of posed expressions and of millions of online videos report shared regularities, which the chapter weighs alongside their limits. Drawing on Scarantino and Griffiths, it treats affect programs as candidate families of fast, ancient responses rather than fixed displays, and uses Del Giudice's work on motivational systems to insist that a model say which quantity it explains.

It then turns to the body's contribution. Damasio's somatic marker hypothesis, built from the patient EVR, holds that learned bodily signals bias choices. The lesion findings stand, but the Iowa gambling task that made the idea famous has fared worse: Maia and McClelland showed that participants could often state the winning strategy, and a 2006 review found the task unable to separate a bodily signal from rival explanations. Craig's model of the insula, and the interoceptive proposals of Seth and of Barrett and Simmons, are presented as theory still awaiting tests; the account of depression as a disorder of allostasis was offered by its own authors as speculation.

Further sections cover fast amygdala responses to fearful faces, stress and the balance between habit and goal-directed control, and Robert Frank's view that emotions such as anger and loyalty solve commitment problems. Experiments on punishment across fifteen populations, Sznycer's finding that reported shame tracks how much others would devalue a person, and research on overgeneral memory in depression each constrain theory without identifying a single mechanism.

The chapter defines precision as confidence in an expectation or a piece of evidence. What matters is relative precision, and it differs from both accuracy and felt intensity, so assigning high or low precision cannot by itself separate feeling from thinking.

Finally it sketches a supervised breathing experiment. If cues predicting heavy resistance make identical loads feel stronger, and more so when bodily signals are harder to read, the conjecture survives; it fails if the effect is absent or if reporting habits or altered breathing explain the results better. Even success would establish only a laboratory process; any role in panic or depression would need separate evidence.

## Questions the chapter asks

- Do facial expressions and bodily responses really reveal a fixed set of universal emotions?
- How much do signals from the body shape what people feel and the choices they make?
- What would a predictive theory of emotion have to claim before an experiment could prove it wrong?
