a summary of the key strategies, tips, tricks, and tactics from Predictably Irrational by Dan Ariely, which explores how irrational behaviors shape decision-making:
Key Strategies, Tips, Tricks, and Tactics
1. The Power of Relativity
- Strategy: Frame choices to make one option clearly superior.
- Tip: Provide a “decoy option” to guide people toward your preferred choice.
- Example: A subscription service offers three options:
- Online-only: $50
- Print-only: $100
- Online + Print: $100
The decoy (Print-only) makes Online + Print feel like a better deal.
2. Anchoring Effect
- Strategy: Use initial information (the anchor) to influence perceptions of value.
- Tip: Present a high starting price or number to set expectations.
- Example: Listing a product’s “original price” (e.g., $200) before showing the discounted price ($120) makes the deal seem more attractive.
3. The High Cost of Free
- Strategy: Leverage the irresistible pull of “free” to drive behavior.
- Tip: Offer a free gift or free shipping to encourage purchases.
- Example: People are more likely to buy a product if it comes with free shipping, even if the cost is slightly higher than the same item without the offer.
4. Social Norms vs. Market Norms
- Strategy: Understand when to use social norms (relationships) or market norms (transactions).
- Tip: Avoid mixing the two; offering money for a favor can hurt relationships.
- Example: Asking a friend to help you move by offering a nice dinner works better than offering $10.
5. The Influence of Expectations
- Strategy: Shape people’s expectations to influence their experiences.
- Tip: Use branding, packaging, and presentation to set positive expectations.
- Example: Wine tastes better to people when they believe it’s expensive, even if it’s the same wine.
6. The Problem with Procrastination
- Strategy: Create systems that reduce procrastination and encourage follow-through.
- Tip: Use deadlines, reminders, or small commitments to motivate action.
- Example: A gym offering a discount for booking sessions in advance helps ensure attendance.
7. Ownership Effect
- Strategy: Highlight the value of ownership to increase attachment and perceived value.
- Tip: Encourage customers to personalize or try the product before buying.
- Example: Test drives for cars or free trials for software make people more likely to buy because they feel ownership.
8. The Influence of Arousal
- Strategy: Recognize how emotions and states of mind affect decision-making.
- Tip: Avoid making important decisions when emotional or stressed.
- Example: People are more likely to overspend during emotional highs, like excitement or anger.
9. The Allure of Options
- Strategy: Limit choices to avoid overwhelming people and improve satisfaction.
- Tip: Offer a curated set of options instead of too many.
- Example: A restaurant with a shorter menu feels less overwhelming than one with hundreds of items.
10. The Effect of Imprinting
- Strategy: Use first impressions or initial experiences to set long-term behaviors.
- Tip: Make onboarding experiences positive to build loyalty.
- Example: A company offering a seamless sign-up process increases the likelihood of long-term use.
11. The Cost of Zero Cost
- Strategy: Offer something completely free to drive irrational decisions.
- Tip: Combine “free” with valuable items to create excitement.
- Example: “Buy 1, Get 1 Free” offers often lead to higher purchases, even if a discount would save more money.
12. The Placebo Effect
- Strategy: Perceptions of quality and value can be influenced by price or branding.
- Tip: Use premium pricing or branding to enhance perceived effectiveness.
- Example: A higher-priced painkiller is perceived as more effective, even if it’s the same as a cheaper option.
13. Loss Aversion
- Strategy: Highlight potential losses rather than gains to motivate action.
- Tip: Frame messages around what people could lose if they don’t act.
- Example: “Save $200 by acting now!” is more compelling than “Earn $200 by acting now!”
14. Herd Mentality
- Strategy: Use social proof to influence decisions.
- Tip: Showcase testimonials, reviews, or statistics about popular behavior.
- Example: “Join over 1 million satisfied customers!” encourages others to follow.
15. Defaults and Opt-Outs
- Strategy: Make desired actions the default choice.
- Tip: Use opt-out settings for subscriptions or donations.
- Example: Organ donation rates are higher in countries where people are automatically enrolled and need to opt out if they don’t want to participate.
