We make decisions based on clues, but we're not always aware which clues we use. Professional persuaders know -- marketers, sales people, pollsters, politicians, merchandisers. Invisible Persuaders helps viewers develop an early warning system to spot subtle attempts to persuade and influence. Examples include:

Appearance: Does good looks influence our opinion of competence?

Positioning: How some merchandise exists not to be bought, but to steer customers to higher profit items.

Colors: How color influences buying decisions.

Branding: A brand name can actually make us believe a product works better than the same product without the brand.

Repetition: Are "hit" songs played often on radio stations because they are popular or are they popular because they're played so often?

Clothing: Do we judge people by their clothing?
