Sales is not just an art but a science — and understanding the science behind human behavior can make every pitch a winner.

1. Sales Ability Can Be Learned and Improved

Sales skills are not innate; they can be learned and enhanced over time. The concept of neuroplasticity reveals that our brains can rewire themselves with consistent effort and practice. This refutes the myth that successful salespeople are always naturally gifted or born with a knack for persuasion.

Instead of relying on anecdotes, using evidence-based strategies grounded in scientific research can lead to significant improvements. Studies reveal that extroverts, often perceived as ideal salespeople, don’t always perform best. Research from the Wharton School demonstrated that highly extroverted individuals often perform worse because they may overwhelm or fail to connect with buyers.

Instead, strategies such as the asymmetric dominance effect show promise. When customers are presented with two choices—one good and one great—the presence of the good option instinctively makes the great option seem more appealing. These scientifically validated methods prove that skill, rather than luck or natural ability, drives reliable outcomes.

Examples

  • Neuroplasticity enables people to develop skills such as strategic questioning with practice.
  • Extroverted salespeople may lose deals by appearing overly pushy or unrelatable, backed by Penn studies.
  • The asymmetric dominance example shows buyers are likelier to purchase when presented with good and great options side by side.

2. Answer the Six Whys to Close Deals

When making a purchase, buyers subconsciously ask themselves six key questions. Addressing these questions can smooth the buying process and remove nearly all obstacles to finalizing the sale. It’s not just about why your product is good—it’s about systematically addressing each step.

First, buyers ask “why change?” Treading unknown ground feels risky, so sellers must show what’s wrong with sticking to the status quo. Next, they ask "why now?" and require a reason to act immediately, such as a time-sensitive discount. Arguing for your industry comes next, justifying why this type of product is the right choice. From there, buyers wonder, "why your company?" and "why your product?" Specific standout features or a track record of success build trust here.

Lastly, buyers consider “why spend the money?” Beyond explaining costs, sellers must highlight the value the purchase offers, such as saving time, increasing efficiency, or minimizing financial risks.

Examples

  • Explaining the urgency of buying now by citing expiring discounts incentivizes quicker decisions.
  • Pitching the industry’s future growth strengthens interest in broader categories, like online courses over traditional schooling.
  • Financial benefits like cost savings or loss prevention seal the deal by justifying expenditures.

3. Positive Moods Drive Buyer Decisions

Emotions influence decisions far more than logic. Studies show that people in good moods are more open to persuasion, making emotional resonance an untapped lever for closing sales. For instance, even judges make more favorable rulings after lunch, highlighting how small environmental factors affect decision-making.

Creating a positive atmosphere elevates mood and facilitates smoother negotiations. Salespeople can lift emotions actively with small gestures like offering snacks, a strategy proven by behavioral scientist Irving Janis. Non-verbal cues also play a role; smiling and maintaining upbeat energy are contagious, making conversations more receptive.

Additionally, casual conversation allows buyers to associate purchases with pleasure, whether drawing on recent happy moments or discussing a hobby. These shifts create memorable emotional contexts tied to the sale.

Examples

  • Judges grant more lenient sentences post-lunch, showing hunger impacts decisions.
  • Offering peanuts and soda in a study led to increased persuasive success rates.
  • Friendly chit-chat about a client’s recent vacation relaxes tense interactions.

4. Ask Questions That Shape Answers

Questions are a powerful tool that can shape the buyer’s thought process. Cognitive processes like instinctive elaboration mean that when a question is posed, people will mentally focus on it, which helps align their thoughts with the salesperson’s goals. This natural reaction makes questions an ideal starting point for effective pitches.

Start with broad questions. General inquiries build rapport while setting the stage. Then, progress to more specific ones once the relationship is established. For instance, beginning with “how is business?” opens the door to detailed discussions, narrowing down issues and needs.

Social penetration theory emphasizes revealing information in stages—peeling layers—making this approach both logical and emotionally resonant. Structured inquiries map a clear progression toward uncovering what the buyer values most, ensuring relevance in your pitch.

Examples

  • Merely asking someone if they plan to vote increases voter turnout, highlighting behavioral shifts.
  • Asking how performance was last quarter guides clients to their pain points seamlessly.
  • Progressing from “Is efficiency a priority?” to “Would faster software help solve workflow issues?” refines focus.

5. Understand Your Buyer’s True Needs

Just as the sisters quarreling over an orange overlooked each other’s needs, salespeople often miss what buyers actually care about. Many spend too much time highlighting features they assume are important rather than addressing the buyer’s fundamental problems.

Top-performing salespeople excel by empathizing with the buyer's perspective. Psychologists warn against inattentional blindness, which blinds sellers to a client’s priorities. By asking problem-focused questions, sellers can uncover what buyers truly need—whether it’s price, convenience, performance, or something else.

For example, a company upgrading tech systems may prioritize faster customer service solutions over price tags. Addressing these motivators instead builds trust and aligns the product with real desires, increasing conversion rates.

Examples

  • An orange’s peel and juices presented clearer needs for the sisters, avoiding waste.
  • Companies focused solely on price discounts miss customers who prioritize durability.
  • Listening to a buyer’s daily challenges reveals hidden win-win scenarios.

6. Show the Value in Real, Tangible Terms

People like to feel like they’re getting a deal. Social exchange theory highlights this drive for favorable outcomes. For salespeople, it’s crucial to translate product features into specific benefits directly aligned with what buyers want.

Don’t just list technical attributes—explain how they solve real problems. A tax software’s fact-checking capabilities sound technical until one connects it to financial savings, reduced mistakes, and audit-proof reporting. Context transforms it into a meaningful purchase.

Additional value comes from diminishing competitors. Calling attention to what rivals can’t offer “inoculates” the customer from future second-guessing.

Examples

  • Tax reporting tools promoted based on financial rewards show results from reduced error rates.
  • Highlight an exclusive feature missing from rivals, such as better cost tracking functions.
  • Comparing shoes’ durability side-by-side demonstrates long-term savings instead of upfront costs.

7. Simplify Choices for Better Decisions

Offering too many options may overwhelm customers, as Iyengar and Lepper’s research into jam varieties demonstrates. Minimizing options increases clarity and confidence for buyers.

Using psychological techniques like anchoring also steers perceptions. When a pricier competitor sets an expectation, your product feels like a steal in comparison. Similarly, presenting offers within stories simplifies complex details in ways the brain remembers emotionally.

Great presentations guide decisions, leaning on fewer, clearer choices and recognizable gains.

Examples

  • A grocery store switching from 24 jams to 6 saw sales soar by 900%.
  • Story frameworks inspire emotional connection with real-life examples.
  • Presenting $500 wine bottles first creates $30 wines seeming much more appealing.

8. Storytelling Beats Straight Facts

Humans remember narratives better than bullet points. Scientific frameworks like the narrative paradigm explain how storytelling bypasses logical skepticism and connects emotionally. Buyers who connect emotionally are likelier to act decisively.

Introduce conflict-resolution structures for your products. Show customers what dilemmas others endured and how outcomes improved with your help.

Examples

  • Talk about struggling small businesses stabilized using your tax software.
  • Create fictional scenarios anchored in customer success.
  • Emotional stories humanize abstract benefits, tilting decisions.

9. Use Science to Build Sales Strategies

Behavioral economics research emphasizes applying brain-based principles thoughtfully. Anchors, emotional moods, storytelling, and limiting confusion multiply credibility and conversion across touchpoints when properly used.

Train around science—it trumps intuition over time. Rational analysis paired with scientific fluency levels up weak guessing games many sellers rely harshly on still.

Examples -Anchoring added logical contrast helps avoid branding fatigue longer-term -Telling more human moments flushes abstract highlights no other approach manages. -Evidence continually replicates overlapping studies actively delivering winning success.

Takeaways

  1. Evaluate and eliminate unnecessary options during sales presentations to avoid overwhelming buyers.
  2. Focus on answering the Six Whys step-by-step to provide clarity and build buyer confidence.
  3. Incorporate emotional storytelling to establish stronger connections and highlight real-world solutions.
