5 Common Negotiation Mistakes (and How to Avoid Them)

Even experienced professionals fall into predictable negotiation traps. Recognising these patterns is the first step to breaking them. Here are five of the most common mistakes and how to fix each one.

1. Anchoring Too Late

Many negotiators wait for the other party to set the first number. While this feels safe, research shows that the first number mentioned in a negotiation has an outsized influence on the final outcome. This is called the anchoring effect.

The fix: Come prepared with a well-researched opening position. If you've done your homework on market rates, competitor pricing, or the value you deliver, lead with confidence. The anchor should feel ambitious but defensible.

2. Talking More Than Listening

Under pressure, most people default to talking: explaining, justifying, filling silence. But the best negotiators spend significantly more time listening. Every word the other party says contains information about their priorities, constraints, and flexibility.

The fix: Practise the 70/30 rule. Aim to listen 70% of the time and speak 30%. Ask open-ended questions and resist the urge to fill pauses. Silence is one of the most powerful tools in negotiation.

3. Failing to Prepare Alternatives

Walking into a negotiation without a clear BATNA (Best Alternative to a Negotiated Agreement) puts you at an immediate disadvantage. Without alternatives, you're psychologically committed to making this deal work, and the other party can sense it.

The fix: Before any negotiation, identify at least two realistic alternatives. What happens if this deal falls through? Having genuine options gives you the confidence to walk away, which paradoxically makes a deal more likely.

4. Making Unilateral Concessions

When pressure mounts, it's tempting to offer concessions to keep the conversation moving. But every concession you make without getting something in return trains the other party to push harder.

The fix: Adopt a "give to get" mindset. Every concession should be paired with a request. "I can meet you on delivery timeline, but I'd need to adjust the payment terms." This maintains balance and signals that your concessions have value.

5. Neglecting the Relationship

Focusing exclusively on the deal terms while ignoring the human element is a recipe for short-term wins and long-term losses. People do business with people they trust, and trust is built through genuine rapport.

The fix: Invest time in understanding the other person's perspective, pressures, and goals. Small gestures like remembering a detail from a previous conversation or acknowledging their constraints build the kind of trust that leads to better deals for everyone.
