Turns out, illeism improves one's objectivity and decision-making skills:

Instead, the scientific research suggests that you should adopt an ancient rhetorical method favoured by the likes of Julius Caesar and known as ‘illeism’ – or speaking about yourself in the third person (the term was coined in 1809 by the poet Samuel Taylor Coleridge from the Latin ille meaning ‘he, that’).

A bulk of research has already shown that this kind of third-person thinking can temporarily improve decision making. Now a preprint at PsyArxiv finds that it can also bring long-term benefits to thinking and emotional regulation.

Grossmann’s aim is to build a strong experimental footing for the study of wisdom, which had long been considered too nebulous for scientific enquiry. In one of his earlier experiments, he established that it’s possible to measure wise reasoning and that, as with IQ, people’s scores matter. He did this by asking participants to discuss out-loud a personal or political dilemma, which he then scored on various elements of thinking long-considered crucial to wisdom, including: intellectual humility; taking the perspective of others; recognising uncertainty; and having the capacity to search for a compromise. Grossmann found that these wise-reasoning scores were far better than intelligence tests at predicting emotional wellbeing, and relationship satisfaction – supporting the idea that wisdom, as defined by these qualities, constitutes a unique construct that determines how we navigate life challenges.

Working with Ethan Kross at the University of Michigan in the United States, Grossmann has also looked for ways to improve these scores – with some striking experiments demonstrating the power of illeism. In a series of laboratory experiments, they found that people tend to be humbler, and readier to consider other perspectives, when they are asked to describe problems in the third person.
