Picture this scene: a board meeting has just ended where everything flowed perfectly. The members were completely aligned, the atmosphere was friendly, and at the end there was laughter and spontaneous applause. You leave thinking: “What great chemistry we have!” Yet, as you walk to your car, an uncomfortable question follows you: “Did we really make the best decisions, or do we simply get along too well?”

Many directors confuse personal harmony with strategic effectiveness. But the research on group dynamics reveals something troubling: excessively good chemistry can lead to the dreaded “groupthink” — the phenomenon described by Irving Janis, in which the desire for harmony replaces critical thinking.

The silent danger of groupthink

When board members feel too comfortable with one another, the likelihood of questioning, debating, or challenging an idea drops dramatically. This carries significant risks:

In analyses of the 2008 financial crisis, work published in the Harvard Business Review highlighted how several highly cohesive boards ignored clear warning signs of risk out of fear of internal dissent. Iconic companies such as Lehman Brothers and Bear Stearns paid dearly for the excessive harmony of their directors.

Positive tension as the key to success

The balance between harmony and productive tension may seem contradictory, but it is exactly what boards need in order to thrive. Leading companies such as Netflix and Amazon actively promote internal debate and cognitive diversity in order to make robust, well-grounded decisions.

To achieve this, successful boards implement practices such as:

A study by the MIT Sloan Management Review found that companies with high cognitive diversity reported 20% more innovation in their processes and products.

How to avoid the trap of excessively “good chemistry”

Reflection questions for the board

  1. When was the last time someone put forward a radically different opinion in a meeting, and how was it received?
  2. Do we have clear processes to ensure that all voices, especially dissenting ones, are heard and considered?
  3. Is our board sufficiently diverse in thought, experience, and perspective, or do we tend to seek very similar profiles?
  4. Have we confused cordiality with strategic effectiveness, avoiding difficult topics to keep the atmosphere pleasant?

Conclusion

Chemistry among board members can be a valuable asset, as long as it does not turn into complacency. The key lies in balancing harmony with enough positive tension to allow for informed, well-debated decisions.

P.S. If no one on your board questions anything, the real chemistry you need may be more tension and less comfort.
