Dear Dan,

I lead a team of designers, and I want to foster an environment where everyone feels comfortable speaking up when they have concerns or new product ideas. I thought about holding a weekly “coffee chat,” where I invite employees to share input on a topic of the week. Do you think that’s a good idea?

—Hansen

The key word is here is “everyone”: Getting your whole team to participate will be difficult. And most managers will tend to overvalue such participation, rewarding and promoting the employees who exhibit it over the ones who don’t.

This finding comes from a study of employees and their managers at a large technology company. Managers were asked to rate the degree to which each employee spoke up to suggest new ideas or offer solutions. The researchers found that employees who were seen as proactive in this regard tended to be rewarded with promotions and salary increases. An employee’s level of day-to-day productivity, on the other hand, was not rewarded to the same degree.

We don’t really want to reward people more for one kind of contribution than for another that is at least as valuable. But managers tend to notice the proactive employees and thus to favor them. So if you want a free flow of ideas but don’t want to fall prey to this bias, you should ask the people working with you to have such meetings over coffee, but you yourself should be absent, and you should ask your employees to share with you the ideas from the group as a whole without noting who contributed which ideas.

Dear Dan,

My teenage daughter is looking at colleges and she’s stressing out about where she should apply. I’m happy to offer her guidance, but most of the time my input isn’t welcome. In fact, sometimes she does the exact opposite of what I advise. How should I proceed?

I also have teenagers. The good news is that they grow out of this in 10-20 years.

In the meantime, consider that your teenager may be exhibiting something that is known as “psychological reactance”: People tend to double down on asserting their freedom when they feel that it is being threatened. This behavior is a psychological counter-measure to a perceived restriction of agency and not a sign of disrespect. It explains why people sometimes do the exact opposite of what is suggested to them.

You are most likely dealing with some reactance. The question is how you can reduce its power.

A recent study suggests one approach. Students were assigned an activity that made them feel either certain or uncertain about their understanding of education. Afterward they were presented with a policy giving the school the responsibility to select their classes. Students who had been made to feel uncertain were much less threatened by the prospect of giving up their freedom than those who had been made to feel certain.

With this in mind, I recommend that you start by shaking your daughter’s belief that she has all the answers. Once you get her to hold a more realistic view of her own knowledge, she can begin to accept your advice.
