Daily brief research updates from the cognitive sciences
When it comes to teams, we like to think of team cohesion and getting on well together which often aligns with team performance. In fact, we at leading brains have developed team assessments measuring just this.
We however, also state that a certain amount of misalignment, diversity of opinion is a good thing – just too much misalignment and disagreement blocks effectiveness of the team. And this research into military teams also shows something interesting in disagreements.
The researchers from the U.S. Army Research Laboratory investigated identification of armoured vehicles in 29 two-person teams. Identifying types of armoured vehicle is essential in combat: you could fire on a friendly vehicle or let an enemy vehicle pass. Armoured vehicles are also difficult to distinguish apart particularly when viewing with limited angles or under time pressure.
What they found is that teams that disagreed more were better at combat identification. This may seem slightly counter-intuitive – with the assumption that high-performing teams would be better at first-off identification and therefore disagree less. However, it seems that disagreeing with a first guess forces people to justify their opinion, and this created more clarity and potential corrections.
This raises an interesting perspective in business teams that disagreeing with a person’s point of view could lead to better discussions and therefore better decisions. Assuming this can take place with the right atmosphere. So, disagreeing should be seen as a positive thing to do to engage in better decision-making.
Another note is that in this particular study they did further analysis of the abilities that contribute to correct identification. What they noticed is that spatial abilities are important to identification of the correct vehicles, unsurprising. But also, that the ability to communicate was essential.
In addition, they analysed gender and saw no correlations to gender composition of teams. So individual spatial skills and ability to communicate were the key factors irrespective of gender.
So, all in disagreements are good, specific skills also, and communication abilities are key.
This was in a very specific scenario, I know, but I assume much of this translates to functional teams of all sorts in the military and business. Indeed, plenty of other research has also pointed to these as being essential attributes of high-performing teams. So go ahead and disagree at your next meeting.
