Thermometer or thermostat?

In family practice, heightened emotions are not the exception; they are the norm. Whether in negotiations, correspondence or mediation, practitioners regularly encounter clients – often the opposing party – whose emotional reactions can quickly derail progress. A simple but powerful framework can help bring clarity to these situations: are you, and is your client, operating as a thermometer or as a thermostat?

A thermometer reflects the temperature of its environment. In practice, this translates into reactivity. A client who receives a hostile message responds in kind. A provocative allegation triggers a defensive or escalatory reply. The focus shifts from resolution to reaction. Before long, the original purpose of the communication is lost, replaced by a cycle of accusation and rebuttal.

A thermostat, by contrast, sets the temperature. It does not ignore what is happening, but it remains anchored to a chosen position. Applied to family practice, this means approaching each interaction with intention: maintaining a consistent tone, staying aligned with the desired outcome and resisting the pull of emotional escalation.

This distinction matters more than it might first appear. When clients operate as thermometers, negotiations tend to become protracted and costly. Positions harden, correspondence deteriorates and the scope for constructive dialogue narrows. In contrast, when clients are supported to act more like thermostats, discussions are more focused, opportunities for settlement increase and the emotional and financial toll of the process is reduced. The practitioner’s role is often to interrupt reactivity and restore a sense of direction.

One of the most effective ways to do this is by helping clients define the purpose of each interaction. Before sending an email, attending a meeting or engaging in a discussion, it is worth asking a simple question: what is this for? Without a clear answer, clients are easily drawn into revisiting past grievances, responding to personal criticisms or engaging with issues that have little bearing on the outcome. A clearly defined purpose provides an anchor, particularly when emotions begin to rise.

Many clients describe a familiar pattern. A conversation begins with a practical objective, such as agreeing arrangements for children, but quickly shifts when the other party introduces blame or raises historical issues. The client feels compelled to respond, often defensively, and within moments the discussion has moved far away from its original aim. This is the thermometer dynamic in action.

Supporting a client to become a thermostat involves preparation as much as it does communication. It means encouraging them to decide in advance how they want to show up, what they are willing to engage with and what they are not. It also involves equipping them with language that allows them to acknowledge the other party without becoming entangled in the emotional content. A simple redirection, calmly repeated if necessary, can be far more effective than a detailed rebuttal.

It is equally important to give clients permission not to engage. Many feel a strong need to respond to every point raised, particularly when accusations are made. Reframing success can be helpful here. Success is not winning the argument; it is maintaining composure, staying aligned with the objective and avoiding unnecessary escalation.

A common example arises around arrangements for children during school holidays. A client may approach the discussion with the clear aim of agreeing dates, only for the other party to revisit perceived past failings or accuse them of poor communication. A thermometer response would involve defending those accusations and countering them, often leading to further conflict and no agreement. A thermostat response, on the other hand, keeps the focus firmly on the present issue. The client acknowledges the other party’s frustration but redirects the conversation back to the practical question that needs to be resolved. While this does not guarantee immediate agreement, it prevents the situation from deteriorating further and keeps the possibility of resolution open.

Practitioners play a crucial role in modelling this approach. A measured, neutral and purposeful style of communication can help regulate the overall tone of the dispute. Equally, reframing a client’s reactive draft into a more constructive message is not simply a matter of presentation; it is an intervention that can influence the trajectory of the case.

Encouraging clients to move from thermometer to thermostat is not about suppressing emotion. It is about creating enough structure and awareness to prevent those emotions from dictating decisions and behaviour. This shift, while subtle, can have a significant impact on the efficiency of the process, the durability of agreements and the client’s overall experience of the separation.
