Using ‘It’s My Birthday!’ to Influence Negotiations
A reflective conversation with Fred Copestake on how personal details, such as birthdays, influence reciprocity, mood, and decision-making in negotiations.
What We Explored in This Episode
In this episode ofThe Negotiation Club Podcast, Philip Brown (Founder of The Negotiation Club) is joined by his good friend Fred Copestake to explore an unexpected negotiation moment that began with a simple statement: “It’s my birthday.”
What started as a casual remark during a past negotiation practice session led to a surprising outcome—one that prompted both reflection and laughter. The episode uses this moment to examine how personal details can quietly influence negotiation dynamics.
Why Personal Details Change Negotiations
Philip and Fred explore why sharing personal information, such as a birthday, can shift behaviour at the negotiation table. One explanation discussed is reciprocity—when someone shares something personal, it can subconsciously encourage the other party to respond with goodwill or flexibility.
The conversation also touches on mood enhancement. Celebratory or positive cues can lighten the tone of a negotiation, making parties more open, collaborative, and willing to explore agreement.
Building Rapport Without Losing Credibility
A key theme is the balance between human connection and professionalism. Personal details can help negotiators appear more relatable and approachable, fostering trust and empathy. However, the episode is clear that this approach carries risk.
Used clumsily or too deliberately, personal disclosures can feel manipulative or insincere, potentially undermining trust rather than building it. The effectiveness of this tactic depends heavily on authenticity and timing.
The Risk of Overusing Emotional Leverage
Philip and Fred also reflect on the dangers of leaning too heavily on emotional cues. While Fred admits the birthday revelation influenced him more than he expected, both agree that negotiators must remain alert to how such tactics are perceived.
The lesson is not to avoid personal details, but to use them sparingly, naturally, and with awareness of the other party’s reactions.
Turning the Idea into Practice
Inspired by the episode, a dedicated “It’s My Birthday” Negotiation Card has been created to help practitioners explore this tactic deliberately.
To practise, try introducing a genuine personal milestone at an appropriate moment in a low-risk negotiation or practice setting. Observe:
The aim is not to manipulate, but to understand how human moments influence judgement and decision-making.
Used thoughtfully, this tactic highlights an important reminder: negotiations are conducted by people first, not positions.
