We should all be aware of the potential impacts of poor design, or the role of design in symbolic politics and agitprop; much less acknowledged are the more insidious effects of design-as-environment.All underscore Winhall's point: design is a powerful tool with significant political implications. She argues this gives designers political and social responsibilities that are virtually ignored in the design industry today.
While I'm not in a position to pass judgment on that industry, so many aspects of design are inherent to teaching that I think educators would benefit from listening to her argument.
When was the last time you used PowerPoint, or moved chairs into a circle?
Thanks to Josh Porter for the link (he also has an interesting follow-up to Winhall).
