Book Review: Predictably Irrational-How Hidden Forces Shape Our Decisions by Dan Ariely

“We are not as rational as we think we are, but we are rational enough to think we are rational.” -Dan Ariely

Predictably Irrational by Dan Ariely is a thought-provoking book that delves into the realm of behavioral economics and the irrationality of human decision-making. Ariely, a professor of psychology and behavioral economics, provides an engaging and informative book that explores the various ways in which people make decisions, often in ways that are not rational or logical.

The chapters are divided into different aspects of human behavior. Ariely uses a combination of personal anecdotes, experiments, and studies to illustrate his points, making the book an easy and thought-provoking read.

One of the key themes of Predictably Irrational is the idea that people often act against their own best interests. Ariely argues that people make decisions based on emotions and biases rather than rational thought, resulting in poor decision-making and negative outcomes. For example, he highlights the concept of “anchoring,” where people rely too heavily on the first piece of information they receive when making a decision, even if it’s irrelevant or inaccurate.

Another important theme of the book is the idea that people are highly influenced by social norms and peer pressure. Ariely explains how our desire to fit in and be accepted can lead us to make irrational decisions, such as conforming to group norms even when they go against our own beliefs.

The style of the book is informative and engaging, with Ariely’s examples making complex concepts easy to understand. However, it’s worth noting that Predictably Irrational is not a book that provides easy answers or quick fixes. Instead, it challenged me to rethink my assumptions about human behavior and the decision-making process.

As a sales professional, I found the insights in Predictably Irrational to be incredibly applicable. The book helped me understand the ways in which customers make decisions, and how I can use this knowledge to deliver a more customer centric sales approach. For example, by understanding the concept of anchoring, I can present my products and services in a way that sets a positive first impression and reduces resistance.

Dan Ariely provides several insights around pricing and purchasing behavior. One key insight is that people’s perception of value is often influenced by the price of a product or service. For example, Ariely found that people are more likely to perceive a wine as tasting better if they are told that it is more expensive, even if the wine is actually the same as a cheaper option.

Another insight is that people are often willing to pay more for a product or service if they feel that they are getting a “deal”. Ariely found that people are more likely to buy a product that has a higher price with a discount than a lower-priced product with no discount, even if the actual price paid is the same.

Ariely also argues that people are more likely to make a purchase if they have an emotional connection with the product or service. For example, people are more likely to buy a product if it is presented in a way that appeals to their emotions or personal values.

Ariely’s insights around pricing and purchasing behavior suggest that people’s decision-making when it comes to buying products and services is often influenced by emotions, biases, and perceptions of value. Understanding these factors can help businesses and sales professionals to develop more effective pricing and marketing strategies.

Overall, Predictably Irrational is a must-read for anyone interested in behavioral economics, psychology, or human decision-making. While it’s not a book that provides easy answers or guarantees success, it’s a fascinating exploration of the science behind our choices and a valuable tool for anyone looking to improve their sales results. My only criticism of the book is that it occasionally feels repetitive, with some of the concepts being revisited multiple times. However, this is a minor quibble in an otherwise excellent read.

10 Strategies to prevent:”I lost the customer to price”

Dilbert on Price

Nothing happens until a sale is made. There are a lot of things that have to happen before a customer signs on the dotted line, but lastly, a sales rep and customer must agree on a price. At one time or another, we’ve all had our prices challenged. I’ve heard many sales people proselytize their closing abilities and tactics. The question becomes of these great closer’s is, have they protected price and margins? It doesn’t take an expert sales person to seal the deal when they’ve simply folded on price once the customer posed a pricing concern.

Avoid Price Driven Conversations

To persevere through pricing objections, your self-assurance is critical. Being confident in what you say is paramount in presenting price (Want a 1:45 second course on CONFIDENCE ?) When the customer requests a discount, respond by asking, “before we get into that, what value do you see in what I’ve presented thus far?” In reality if a customer can’t, or refuses to, answer that question, then the decision is made solely on price and I bet there are other cheaper options for your customer.

The worst thing sales people can do when a customer is looking for a price break is to give in. Jeb Blount, author and sales expert, states that customers may not have gone to sales university, but they’ve definitely gone to buyers university. Many customers know that if they give the least bit of price resistance a sales person will immediately offer price concessions. To overcome this problem, sales people need to understand, in real terms, how their prospect can benefit from your product or service- from their perspective.

A great example that I learned from Keith Rosen. If I’m taking a trip and my destination is 1,000 miles away, I have several options. I could hitchhike, which would cost me virtually nothing, but wouldn’t guarantee when I’d arrive. I could drive my car, limiting my immediate costs to the necessary gasoline, but my trip could take several days. Or, I could fly, which would probably be my highest-priced option, but would be the fastest.

You can see from my travel example that the cheapest option is not reliable, nor would it save time. In addition, most people wouldn’t want to take several days to drive to and from their destinations. Therefore, because of the time it will save, the best option is to fly, even though it’s probably the most expensive choice. Since time is of the essence for many folks, its value is worth the extra money. Cutting the price is clearly not beneficial or efficient for the customer.

Confidence Is key Everything

To hold firm on price you need to have a high level of confidence. One of the best ways to feel confident is by maintaining a full sales pipeline. When a sales person doesn’t have a full-pipeline, or lacks the ability to generate more customers, or doesn’t fully nurture past customers, they rely on each potential sale that a customer may propose. Sales people become needy, overzealous, and those emotions lead to the inability to overcome price objections.
