Human Limitations and Meeting Agendas

Designing meeting agendas can be tricky business. Considerations include logical flow, partial attendance by those with conflicting commitments, time zone differences, and the politics of the pecking order, among other factors. Recent advances in psychology [Baumeister 2011] are suggesting additional constraints — ego depletion and decision fatigue.

Ego depletion is the idea that we have limited energy available for regulating our own behavior, until we rest and recover. Numerous experiments have produced results consistent with this hypothesis. Closely related is the idea of decision fatigue. People seem to have limited energy available for the kinds of complex trade-offs associated with difficult decisions.

These two phenomena affect meetings in different ways, though they are closely related and often overlapping.

Ego depletion manifests itself when we tire of exerting self-control, as when we stifle expressions of anger or frustration, or when we try to conform to social expectations despite how we really feel. It degrades our ability to control ourselves.

Ego depletion is a risk whenever meeting agendas have the more heated debates at the end of the meeting. (I call such agendas "inverted.") During the meeting, slights, affronts, misunderstandings, and insults are possible. In some meetings, they're likely. Anyone who tries to deal with these incidents by controlling their urges to wring someone else's scrawny little neck, for example, is at elevated risk of ego depletion. By the time we arrive at the last items of an inverted agenda, some people might not have energy enough for self-control. Nasty interactions are more likely. To limit this risk, place at the top of the agenda any debates likely to become heated.

Some meeting chairs actually want some participants to lose control. These chairs might exploit ego depletion to achieve their own devious ends. Beware.

Decision fatigue sets in when we've wrestled with difficult decisions for even a short time, or when we've spent significant time on less-than-critical decisions. Consider the agenda for a meeting in which we rank a series of product defects. Because decision fatigue tends to make us controversy-averse, and because higher severity assignments for defects tend to provoke controversy, defects discussed early in the agenda tend to be classified as more severe.

In meetings In meetings in which we're
allocating enterprise resources,
decision quality degrades
as time goes onin which we're allocating enterprise resources, decision quality also degrades as time goes on. Because increasing resource allocations beyond current resource levels tends to create more controversy, and because decision fatigue makes us controversy-averse, current levels tend to prevail when decision fatigue takes hold. That's one reason why departments seeking significant resource increases tend to do better if they appear near the top of the agenda. Meeting chairs who know about this phenomenon might exploit it. Beware.

Breaks and food can mitigate these effects. Schedule breaks not by the clock, but according to the strenuousness of the effort.  Top    Next Issue

When Naming Hurts

One of our great strengths as Humans is our ability to name things. Naming empowers us by helping us think about and communicate complex ideas. But naming has a dark side, too. We use naming to oversimplify, to denigrate, to disempower, and even to dehumanize. When we abuse this tool, we hurt our companies, our colleagues, and ourselves.

Totally at Home

Getting home from work is far more than a question of transportation. What can we do to come home totally — to move not only our bodies, but our minds and our spirits from work to home?

Hurtful Clichés: I

Much of our day-to-day conversation consists of harmless clichés: "How goes it?" or "Nice to meet you." Some other clichés aren't harmless, but they're so common that we use them without thinking. Maybe it's time for some thought.

Coming December 11: White Water Rafting as a Metaphor for Group Development

Tuckman's model of small group development, best known as "Forming-Storming-Norming-Performing," applies better to development of some groups than to others. We can use a metaphor to explore how the model applies to Storming in task-oriented work groups. Available here and by RSS on December 11.

And on December 18: Subgrouping and Conway's Law

When task-oriented work groups address complex tasks, they might form subgroups to address subtasks. The structure of the subgroups and the order in which they form depend on the structure of the group's task and the sequencing of the subtasks. Available here and by RSS on December 18.
