Not all conflicts in a group are bad
Just as there are many benefits from working in groups, there are also a number of challenges, which may lead to conflicts. But not all conflicts in a group are bad.
Academic or personal conflicts
You can think of conflicts in terms of academic conflicts or in terms of personal conflicts.
When you disagree on an academic level
Academic conflicts can be a constructive way to develop a deeper understanding or to discuss theoretical or methodological differences. Actually, you should not be afraid to go into academic discussion, but make sure you are constructive and argue on a professional level.
If you have a personal conflict
In a group, you are working with people who are different from you, and this can result in personal conflicts due to differences in ambitions, values or experiences. Most conflicts can be solved with the right tools.
