This TedEd presentation considers the issue of political identify (partisanship) and how it can cloud the ability to evaluate an issue that has been politicized (gun ownership). The presentation uses one of the best examples to explain partisanship I have found – that of sports fandom and describes the familiar situation in which fans of competing teams witness the same controversial call. I found this same explanation used in the citation I provide at the end of this post.
The lesson includes a presentation, additional resources, and suggested activities.
The component of this lesson I think could be improved involves the use of identity rather than partisanship to explain the power of this type of bias. As a psychological construct identity is often described of as at the core of how we see ourselves and protecting the way we have come to see ourselves is a strong motivator. This perspective is emphasized in one of the supplemental readings offered and I believe to be the best way to explain why political views are so powerful.
