I had the same reaction to that paragraph, but the very next paragraph is more compelling:

In another experiment, the authors primed CEOs’ narcissistic self-image by asking them to reflect on the role that a bold, assertive ego played in the successes of Apple CEO Steve Jobs and Oracle cofounder Larry Ellison. Afterward, leaders who’d been primed were more likely to oppose working from home, compared with those who weren’t primed. This, the researchers concluded, suggests a causal link between activating ego and opposing remote work.
