My personal experience on group think have not been too much, but there have been 2-3 instances where I have experienced it. So, this is was in my college time when we were given few group tasks for our annual sports meet. The teams were random to test the team building and team leading abilities of participants. The teams had six members per team. We had a task of crossing an obstacle course in the fatest possible time. First things first, instead of appoiting a team leader we directly jumped to discuss the course and put our estimation in front. There was not much input from us and hence we ended up making a common plan for the course. Instead of focusing on different abilities we had or different routes that can be taken in the course we focused on just completing it in the minimum possible time upfront. No one objected the plan, no one said what if or why. It was all yes throughout our discussion or i should say it was all no thoughts just plan thing. When we started performing, we realized that we lacked ideas of understanding the obstacle. We lacked the planning of setting an order to perform task per individual and their strength. In the end we came second to the last.
Remedies for such groupthink can be as follows:
->Plan with a lot of logical what if’s and why’s.
-> Focus on each other’s strength, you never who has the best abilities according to the problem.
-> Don’t focus on just speed, even the hare lost to tortoise once.
-> Initiate a debate, ask each one of the group for their inputs.
