It is a common misconception in business that a little “white lie” to close a deal is harmless, but these unethical sales tactics have significant consequences.
We often see teams telling clients that “stock is running low” when the warehouse is full, or claiming a discount “expires in 2 hours” when it’s actually available all week.
It seems like a small thing. It gets the sale across the line. It boosts the month’s numbers.
However, Dr Robert Cialdini’s research demonstrates that allowing an unethical culture to fester doesn’t just hurt customers; it creates a “Triple Tumor” structure that rots an organisation from the inside out.
Unethical Sales: The High Cost of the Low Road
Using unethical tactics, like fake scarcity or manufactured urgency, might produce short-term results. But as we say at the Cialdini Institute, it is a long-term disaster.
In a recent episode of the ‘Ethical Persuasion Unlocked’ podcast, I discussed these hidden costs with Brian Ahearn, one of the few other Cialdini Institute trainers. We unpacked exactly how encouraging your team to deceive customers or use unethical sales strategies introduces three distinct “cancers” into your business culture.
Cancer 1: Employee Stress and Burnout
Most people are fundamentally decent. They generally dislike the idea that they cannot succeed without lying or cheating.
Research shows that when employees are placed in a position where they feel pressured to mislead a customer with unethical sales tactics to hit a KPI, it creates deep internal conflict. This dissonance spikes cortisol levels and creates chronic stress.
Dr. Cialdini’s research found that unethical work climates correspond directly to diminished job performance and higher levels of workplace stress. The result? Increased sick leave, lower energy levels, and a team that is mentally checked out. You aren’t just losing integrity; you are losing productivity.
Align KPIs with Values
Don’t just measure the result (the sale); measure the method. We recommend implementing Ethical Climate Surveys to identify stress points. Train your managers to explicitly reward staff who choose the honest path, even if it means missing a short-term target. This reduces cognitive dissonance and restores mental well-being. In addition, acting honestly in a way that goes against our own self-interest from time to time will actually activate the principle of authority and build trust and loyalty.
Cancer 2: The Talent Exodus (Staff Turnover)
Who are the first people to leave an unethical organisation?
It is rarely the underperformers. It is the best people.
Talented, ethical performers have options. They often refuse to compromise their values for a paycheck. Experiments have shown a massive disparity in turnover intentions: in one study, 80% of employees in an unethical environment chose to leave their team, compared to just 51% in an ethical one.
When the “churn and burn” mentality becomes standard, top talent leaves to find employers who respect the truth. This leaves organisations with a workforce comprising only those who are comfortable with deception. Source: Research cited in “The Hidden Costs of Organizational Dishonesty” – Cialdini et al.
The ‘Walk Away’ Reward
Create a “Culture of Truth.” Publicly celebrate acts of integrity, like when a team member chooses transparency over a quick sale. By signalling that honesty is valued higher than immediate revenue, you attract and retain high-calibre talent who want to work in a psychologically safe environment. And if you communicate these acts publicly, it will strengthen existing client loyalty and encourage new clients to start working with you.
Cancer 3: Internal Theft (The Sting)
This is the cost that surprises most leaders.
If an organisation hires or retains people who are comfortable cheating customers, it is logical to ask: why wouldn’t they cheat the company?
Dr. Cialdini points out a distinct correlation here. The type of person who is willing to lie to a client is often the same type of person who is willing to pad their expense report, do deals on the side, steal office property or engage in internal fraud.
By cultivating a culture of “sales at any cost,” businesses inadvertently select for employees who lack integrity in all directions—not just when facing the customer. Source: Cialdini Institute – “Why Unethical Persuasion Tends To Backfire”
The Mirror Effect (Tone at the Top)
Leaders must realise they are the mirror. If you cheat a client, you are effectively licensing your staff to cheat you. The resolution is strict Hiring for Character and consistent modelling from leadership. Using frameworks like the “3-Question Test” (Is it Truthful? Is it Natural? Is it Wise?) ensures that honesty is the only standard—internally and externally. Resource: Cialdini, R. B., Petrova, P. K., & Goldstein, N. J.

The Unethical Sales approach is out: The Smart Money is Ethical
There is a misconception that businesses must choose between being ethical and being profitable. This is false.
The smart money is on the ethical way.
Ethical Persuasion, using science to bring to awareness the facts that appeal to the primary decision-making part of the brain and that your audience wants and needs to hear from you to make easier Yes decisions that align with their values, not only works, but it also builds loyal relationships.
And behaviour science doesn’t just work with clients; it also works with team members. It helps you attract top-tier talent through persuasive appeals, and when they realise that an ethical culture is in place, it increases their passion and loyalty to the company and its mission. For client relationships, we can expect strong bonds, more proposals being accepted, greater forgiveness if something goes wrong, and more clients returning year after year.
A serious risk and cost factor to organisations
Organisations lose copious time and resources by failing to use the available science to be persuasive. That’s clear. Using science to develop unethical sales strategies, or accidentally using those strategies, poses a significant risk that they will damage their brand and destroy client relationships. The costs to their team structure can be a significant expense they are not aware of. An ethical, science-driven communication culture can outperform an unethical approach, without the toxic side effects in the short- and long-term.
Protect Your Culture
It is time to audit your sales strategies. Are you using the Science of Influence to reveal the truth, or are you using manipulation to hide it?
Your bottom line—and your best staff—depend on the answer.
