Sales Psychology: The Complete Guide to Brian Tracy’s Psychology of Selling and What Research Says About Selling Skills

Sales psychology is the study and practice of how buyers think and decide, and how salespeople manage their own confidence and fears. Brian Tracy’s The Psychology of Selling (2004) teaches it in two parts: the inner game of the salesperson’s self-concept, and an outer game of questions, presentations and closes.

How we wrote this guide: this guide was written by Saj Ali. It draws on Brian Tracy’s _The Psychology of Selling_ (Thomas Nelson, 2004), Neil Rackham’s research for _SPIN Selling_ (1988) and a meta-analysis of what drives sales performance. Every research claim links to its source.

Sales psychology in brief

• The inner game. Your self-esteem and self-concept shape how well you sell.
• Why people buy. “People buy for their reasons, not for yours.”
• The method. Logical questions, from general to specific, then a natural close.
• What research shows. Successful salespeople in large sales ask more questions; knowledge and adaptiveness drive performance.
• Pairs well with. After-action review and self-concept.

What Is Sales Psychology?

Brian Tracy began his career selling door to door, and his breakthrough came, he wrote, when a top salesman showed him a presentation built on “a series of logical questions, from general to specific” (blank” rel=”noopener”>Tracy, 2004). His audio programme _The Psychology of Selling followed, and in 2004 he published the book, which he called “the written version” of it (Tracy, 2004).

The book’s chapters show how he divided the subject (Tracy, 2004):

Tracy belonged to the same generation of American sales trainers as Zig Ziglar, who started as a salesman for the WearEver cookware company and later wrote Secrets of Closing the Sale (Wikipedia).

The Inner Game of Selling

Tracy taught that selling starts inside the salesperson.

Self-esteem

“Your self-esteem is best defined as ‘how much you like yourself’” (Tracy, 2004). He argued that “the more you like yourself, the more enthusiastic you are”, and that “emotions are contagious”: when you are confident and enthusiastic, “the prospect picks up these emotions from you” (Tracy, 2004). See our self-concept guide.

The self-concept level of income

Tracy described a “self-concept level of income”. If you earn 10 percent or more below it, he wrote, “you will engage in scrambling behaviors” to get back into your “comfort zone”; if you earn 10 percent more than you think you are entitled to, the money “will burn a hole in your pocket” (Tracy, 2004). He presented the 10 percent band as a psychological finding without naming a study, so treat it as his model.

Two fears

• Fear of failure. In the customer, “the fear of failure… is the one greatest obstacle to buying”, because every customer “has made countless buying mistakes” (Tracy, 2004).
• Fear of rejection. In the salesperson, it is eased by accepting that “80 percent of sales calls will end in a no, for a thousand different reasons”, which “does not necessarily mean that there is anything wrong with the salesperson or the product” (Tracy, 2004). That figure is Tracy’s rule of thumb. Our page on fear of rejection has more.

Why People Buy and How to Sell

Why people buy

“People buy for their reasons, not for yours” (Tracy, 2004). Tracy said every customer has three choices with every offer: “He can buy from you, buy from someone else, or buy nothing at all at this time” (Tracy, 2004). The job is to show the customer they will be better off with your product than with either alternative.

The seven key result areas of selling

Tracy listed seven: “prospecting, building rapport, identifying needs, presenting, answering objections, closing the sale, and getting resales and referrals” (Tracy, 2004). He compared them to “the digits in a telephone number”: you must dial each in sequence. See our key result areas guide.

Question-based presenting

Rather than giving a speech, ask questions from general to specific, so that by the end it is “perfectly clear to the prospect that he could use and benefit from our product” (Tracy, 2004).

Closing techniques

Tracy described many closes in The Psychology of Selling (Tracy, 2004), including:

The 80/20 rule in selling

Early in his career, someone told him: “The top 20 percent of salespeople make 80 percent of the money” (Tracy, 2004). He decided to join the top 20 percent. See our 80/20 guide.

What the Research Says

Questions matter in large sales

Neil Rackham’s research team studied 35,000 sales calls in more than 20 countries over 12 years, backed by companies including Xerox and IBM (blank” rel=”noopener”>Wikipedia). The results, published in _SPIN Selling (McGraw-Hill, 1988), found that successful salespeople in larger sales asked more questions, especially about the implications of the customer’s problems, and that many classic closing techniques worked less well in large, complex sales than in small ones (Rackham, 1988). This supports Tracy’s emphasis on questions, and suggests caution with pressure closes in big deals.

What drives sales performance

A meta-analysis by Willem Verbeke, Bart Dietz and Ernst Verwaal examined the drivers of sales performance. The strongest were selling-related knowledge (β = 0.28), adaptiveness (0.27), role ambiguity (−0.25, a negative effect), cognitive aptitude (0.23) and work engagement (0.23) (Verbeke, Dietz & Verwaal, 2011). The authors suggested that salespeople have become “knowledge brokers”.

How to Apply It: Step by Step

1. Score yourself from 1 to 10 on each of the seven key result areas. Work on the lowest first.
2. Prepare a question-based presentation. Write 10 questions that move from general (“How do you handle this today?”) to specific (“What does that cost you each month?”).
3. Find the hot button. Listen for the one result the customer cares about most.
4. Present only what matters to them. Show the features that deliver their main benefit.
5. Use trial closes as natural checks, such as “Is this what you had in mind?”
6. Expect many calls to end in a no. Don’t take it personally.
7. Review every call. Ask “What did I do right?” and “What would I do differently?” (after-action review) (Tracy, 2003).
8. Keep learning. Selling-related knowledge was the strongest driver of performance in research (Verbeke, Dietz & Verwaal, 2011).

Common Mistakes

• Using closes as tricks. Pressure tactics can backfire, especially in large sales. Use closes as natural questions.
• Talking more than listening. Ask, then listen to the answers.
• Selling for your reasons. Find out what the customer wants before presenting.
• Taking a no personally. Many calls end in a no for reasons that have nothing to do with you.
• Skipping key areas. Weakness in one area, such as prospecting, limits results in all the others.

Frequently Asked Questions

What is a trial close?

A question asked during a presentation to check the customer’s interest, such as “Does this make sense to you so far?”

What is the hot-button close?

A technique in which you identify the one benefit the customer cares about most and focus your presentation on it.

What does research say about selling?

Neil Rackham’s study of 35,000 sales calls found that successful salespeople in large sales asked more questions. A meta-analysis found that selling-related knowledge and adaptiveness were the strongest drivers of performance.
