Is The "New Manager Bounce" Real? | Nudge Newsletter


Do new managers give teams a "bounce"?

Read online


In sports, it's common to hear about the "new manager bounce".

It's an immediate improvement in performance following a change of manager.

Like most sporting clichés, it's made its way into the working world.

An old boss of mine justified a managerial replacement. by citing the need to quickly hit that quarter's KPIs.

But is the new manager bounce real?

One detailed study¹ on Polish football managers found that players initially ran faster and farther after a manager was fired.

But this was just a return to normal effort levels prior to the underperforming old manager.

Long-term results didn't improve.

A Norwegian study² compared NFL* teams that fired managers vs. those that hadn't.

Despite having similar performance declines, teams that kept their coaches actually recovered faster.

Those who fired the manager improved far more slowly.

Turns out, replacing a manager rarely provides lasting performance gains — Phill

As a behavioural science practitioner, I believe in the peak-end rule.
