When witnesses appear before select committees, Hansard records their words – but not their expressions. In a blog originally posted on Democratic Audit, Cheryl Schonhardt-Bailey (LSE), analysed nonverbal behaviour in 12 economic policy committee hearings, including some in which George Osborne gave evidence. In some of the hearings with Osborne, he appears to be smirking; in others, his smiles appear genuine. She argues that gestures, expressions and tone may be pivotal in whether a policymaker’s arguments are accepted.
