I was recently on a panel at a local meeting in NYC of Industrial Organizational Psychologists and after much discussion I made a statement. I said that as a field we have almost completely and utterly failed at bridging the gap between the science and research that we do, the evidence-based and experimental knowledge that we gain and those who are out there in the world writing about people at work or organizations in the lay press, or those in organizations, making day-to-day decisions about them which affect both the organizations and the people within them. After all most of the information about people at work is just “common sense” isn’t it? And I am a person and I work, so I guess that makes me an expert.
Unfortunately, much of that “common sense” is not supported by the facts and in some cases the facts support the opposite conclusion or the common sense is generated by those who have an agenda in which facts are simply inconvenient. Here are some of the more common statements that I keep running across that either have no basis in reality, are the opposite of the actual evidence, rest on very shaky expansions or extrapolations of a small kernel of observation, or are based on a small handful of people or organizations at one tail or the other of a distribution, but ignore the vast majority of those in the “fat part” or middle of the distribution.
- Statement: People will find jobs once their unemployment checks run out, a social safety net is an incentive not to work.
o Reality: The vast majority of people want to positively contribute to society, as it makes them feel valued. People want to feel valued, it is a universal. The data show that people would rather be overworked than underworked and the desire to work and contribute is not diminished in societies with strong social safety nets. Can you find people who fit the above statement? Sure, but not the vast majority.
- Statement: The various generations want and expect different things from the work environment.
o Reality: There is simply no evidence to support the notion that different generations want different things from work. Rather the differences often cited are driven by life stage and economic opportunity. In other words, give a person a mortgage and kids in college and job security becomes more important to them. A person right out of college with no responsibilities or financial obligations will act similarly regardless of which generation they come from. Because life stages take a rather long time to get though they give the appearance of being generationally driven.
- Statement: People join companies and leave managers.
o Reality: Are there “bad” managers out there that have driven people out of an organization? Absolutely. But the majority of people join an organization and then leave when they don’t see a promising future for themselves within the organization. Sometimes that feeling is caused by a bad manager, and sometimes by the simply reality of a mismatch between a person’s career expectations and what the organization can offer. And sometimes it is simply a person’s life situation. The next time you are with a large group of people ask for a show of hands of how many of them left their last job because of a bad boss.
- Statement: A good interviewer can determine if a person is a “fit” for an organization.
o Reality: We have known for a very long time that interviewers can actually diminish the ability to predict whether someone will succeed in an organization. An interviewer makes judgments that are often not based on job relevant characteristics.
- Statement: Lie detector tests can determine if someone is lying and can be useful in making hiring decisions.
o Reality: The evidence that lie detectors actually work and can determine if someone is lying is not there. And it is absolutely for certain that people with low affects can lie to lie detectors and get away with it. Lie detectors work on the notion that someone telling a lie will become more stressed and emotional and someone telling the truth will remain calm. The reality is that someone, even an innocent person, hooked to a lie detector and being asked about crimes will become stressed. (Generating false positives.) You might as well tie the person to a log and throw them in a river. If they float they are guilty and should be executed. If they sink and drown they are innocent, but unfortunately still dead.
- Statement: Money doesn’t motivate people on the job.
o Reality: Money is a great motivator (ask those on Wall Street). Money tends to show up on statistically generated lists of drivers of job satisfaction when people perceive themselves are being paid unfairly. When they perceive themselves as being paid fairly for the work they do, it tends to diminish in importance. People who claim money is not a motivator often seem to be people whose job it is to keep employments costs down.
- Statement: It is good to regularly reorganization a company. It keeps people sharp; it keeps them on their toes.
o Reality: Organizations that regularly reorganize are consistently having people learning the ropes of new positions. In several studies it has been shown that better performance is achieved by people who have been in positions for longer periods of time then by people who are switched from job to job.
- Statement: In business downturns, laying-off people is the best course of action.
o Reality: If you can’t afford to pay people you need to get your costs down or you cease to exist. However, there is a good deal of evidence that shows that organizations that resist layoffs in down-cycles outperform as the economy recovers.
- Statement: Women are more risk adverse than men, so if a job requires risk taking women are not a good fit.
o Reality: It is pretty easy to find women who are more risk tolerant than many men. This is bias pure and simple and based on stereotypes.
Many of these statements are what Paul Krugman, the Nobel winning economist and NY Times columnist calls “Zombie Ideas”. Zombie ideas are statements that should have been killed by the evidence but refuse to die. From my perspective the field of Industrial Organizational Psychology, which is often concerned about publishing in scientific journals, (not that there is anything wrong with that), has a lot more work to do in getting our knowledge out into the mainstream and accepted.
