Social influence and persuasion

The first principle

We change what we think and do because of other people far more than we like to admit. Social influence is that change, and it ranges from the gentle pull of a group to the open threat of force. Persuasion is the form that respects the other person's freedom, because it works through reasons and appeals, so the ethical question is always how much free choice the influence leaves behind.

The core

• Conformity is changing behaviour or belief to match a group, without being asked. It comes from wanting to be right (informational influence) or wanting to be accepted (normative influence).
• Compliance is agreeing to a direct request, often without private agreement. Tactics such as the foot in the door, a small request first and then a larger one, increase it.
• Obedience is following an order from someone seen as a legitimate authority, and in hierarchies such as the civil service it is the strongest form of everyday influence.
• Persuasion changes attitudes by communication. Its effect depends on the source (credibility, likeability), the message (evidence, emotion, framing) and the audience (interest, prior views, ability to think it through).

Dimensions

• Group norms: groups develop unwritten rules about what is normal, and these can be good, such as punctuality, or harmful, such as an office where everyone takes speed money. Groupthink, a term from Irving Janis, describes cohesive groups suppressing doubt to keep harmony.
• Persuasion routes: the elaboration likelihood model separates thoughtful persuasion from persuasion by cues, which explains why some campaigns change behaviour for years and others only for weeks.

In practice

• Coercion and undue influence in law: the Indian Contract Act, 1872 defines coercion (section 15) as committing or threatening acts forbidden by the Indian Penal Code, or unlawfully detaining property, to make a person agree. It defines undue influence (section 16) as a person in a position to dominate another's will using that position to obtain an unfair advantage. The same distinction helps to understand pressure at work.
• At work: a threat of transfer or an adverse entry to force an officer to sign is coercion. A senior who uses his standing and the junior's dependence to "suggest" that a file be cleared is exercising undue influence, even if no threat is spoken.
• Swachh Bharat Mission (2014): besides building toilets, it relied on community led efforts and village level declarations of open defecation free status, using social norms and collective pride to change behaviour.
• Give It Up (2015): better off LPG consumers were urged to give up their cooking gas subsidy voluntarily, an appeal to fairness rather than a rule.
• Economic Survey 2018 to 19: it devoted a chapter to behavioural economics and argued for using nudges in policy, citing such campaigns.

Issues and way forward

• Blind obedience to unlawful orders, because hierarchy rewards compliance. Insisting on written orders and recording dissent, as civil service rules allow, keeps the officer accountable to law rather than to persons.
• Manipulation instead of persuasion, because fear and misinformation work fast, especially online. Public campaigns should be honest, transparent about who is behind them and based on evidence.
• Nudges can slide into control, because they act below conscious thought. They should be open, easy to refuse and in the citizen's own interest, which is the test Thaler and Sunstein themselves proposed.

Common confusions

• Conformity and compliance. Conformity follows a group without any request. Compliance answers a direct request from someone.
• Coercion and undue influence. Coercion overrides consent openly through threat or force. Undue influence corrupts consent quietly through a relationship of dominance or trust.
• Persuasion and manipulation. Persuasion offers reasons the listener could examine and reject. Manipulation exploits weaknesses or hides the truth so the listener cannot judge freely.

• Introduction lines:
  • In Milgram's experiments of the 1960s, about two thirds of ordinary participants obeyed an authority up to the highest shock level, which shows how easily orders override conscience.
  • The Indian Contract Act, 1872 separates coercion from undue influence, and the distinction carries over neatly to pressure in the workplace.
• Conclusion lines:
  • The state may persuade its citizens, but it must do so openly, with honest reasons and respect for their freedom to say no.
  • An officer who understands social influence can resist its harmful forms and use its good forms to change behaviour for the public good.
