BOSTON — Anyone who’s ever been so furious with their boss that they feel like exacting revenge really needs to listen to Lindie Liang.

Liang and her colleagues found that abusing a virtual voodoo doll instead of your boss will make you feel better without getting you fired or thrown in jail, according to a study that earned them a 2018 Ig Nobel, the annual prize sponsored by the science humor magazine Annals of Improbable Research for comical but practical scientific discovery.

Winners recognized Thursday included a Japanese doctor who devised a revolutionary new way to give yourself a colonoscopy; a British archaeology lecturer who figured out that eating human flesh isn’t very nutritious; an Australian team that found that people who buy high-tech products really can’t be bothered with the instruction manual; and Spanish university researchers who measured the effects of shouting and cursing while driving.

The prizes at the 28th annual ceremony at Harvard University were handed out by real Nobel laureates. The event featured a traditional paper airplane air raid and the premiere of “The Broken Heart Opera,” performed with the help of Harvard Medical School cardiologists.

The winners, who as usual journeyed to Massachusetts at their own expense, also received a cash prize of 10 trillion virtually worthless Zimbabwean dollars. Each was given 60 seconds to deliver an acceptance speech before an 8-year-old girl complained onstage: “Please stop. I’m bored.”

Liang, an assistant professor of business at Wilfrid Laurier University in Waterloo, Ontario, specializes in studying workplace aggression.

“We wanted to understand why subordinates retaliate when it’s bad for them,” she said. “We all know yelling at our boss is bad for your career. So what’s the function of retaliation? Why do people keep doing it?”

People were shown an online voodoo doll with their supervisor’s initials. They had the option to use pins, pliers or fire on the virtual doll. The bottom line: People felt better after abusing the doll.
