British advertising executive Rory Sutherland coined the term “doorman fallacy” in his 2019 book Alchemy. Sutherland uses the concept of the humble hotel doorman to illustrate how businesses can misjudge the value a person brings to the role.

To a business consultant, a doorman appears to simply stand by the entrance. They engage in small talk with those coming and going, and occasionally operate the door.

If that’s the entirety of the job, a technological solution can easily replace the doorman, reducing costs. However, this strips away the true complexity of what a doorman provides.

The role is multifaceted, with intangible functions that extend beyond just handling the door. Doormen help guests feel welcome, hail taxis, enhance security, discourage unwelcome behaviour, and offer personalised attention to regulars. Even the mere presence of a doorman elevates the prestige of a hotel or residence, boosting guests’ perception of quality.

When you ignore all these intangible benefits, it’s easy to argue the role can be automated. This is the doorman fallacy – removing a human role because technology can imitate its simplest function, while ignoring the layers of nuance, service and human presence that give the role its true value.
