The Harvard Business School released a study that points to the use of small gadgets as a reason that people are less likely to take initiative or willing to go out of their comfort zones. The larger the gadgets used, the more assertive participants were.

When people use smaller devices, their posture contracts, increasing stress and decreasing testosterone levels, say researchers Maarten Bos and Amy Cuddy of Harvard Business School. The inverse is true when people use large desktop computers, which force users to assume a more open posture. And the effect continues even after the device is put away or the user logs off.

So the next time you’ve got a presentation to give or networking to do, it might be better to leave the smartphone at home.

Read the rest of the study’s findings at the Wall Street Journal.
