Influence and Persuasion
HBR Emotional Intelligence Series
by Harvard Business Review
The big idea
Influence and persuasion are learnable, research-backed skills built on both broad frameworks and small, specific tactics, and this HBR collection's throughline is that emotional appeal, not just logic and data, is often what makes a persuasive message land.
The anthology includes Robert Cialdini's Harnessing the Science of Persuasion, which lays out research-based levers of influence such as reciprocity, social proof, authority, consistency, liking, and scarcity. The collection frames these as tools to combine deliberately, for example pairing a small favor with visible evidence that respected peers already agree, rather than relying on any single lever alone.
Cialdini's principles are broader work of his own reprinted and summarized in this HBR article; this booklet is not the original source of the framework, just one place it's collected.
Key ideas
Influence has identifiable components
One piece breaks influence down into specific components leaders can practice individually rather than treating it as one vague trait.
A handwritten note measurably increases compliance
One piece cites research that adding a small personal touch to a routine request significantly raises the odds someone follows through.
Charisma can be taught, not just inherited
Specific, learnable behaviors, like using rhetorical devices and confident nonverbal delivery, create the perception of charisma.
Storytelling changes how people receive information
A well-told story bypasses resistance that a fact-based pitch alone triggers, because it engages emotion alongside logic.
Try it this week
- In your next request for help or buy-in, add one small personal touch, a handwritten note or a specific personal reference, rather than sending a generic ask.
- Pick one recurring update or proposal and rewrite it once as pure data and once as a short story, then decide which fits the audience and stakes better.
Is it for you?
Best for
- Managers who want tactical, article-length techniques for a specific presentation, pitch, or negotiation
- People who want Cialdini's persuasion research summarized alongside practical workplace applications
Less useful if
- Readers wanting a single coherent authorial voice or a from-scratch education in persuasion theory
- Anyone uncomfortable with the collection's frank how-to-get-people-to-say-yes framing
