Friday Feedback Favourites

Each Friday, I share a collection of stories, research, or other news and notes related to the role of feedback in complex systems that catch my attention during the previous week. Most I share on twitter when I first read about them; if you have a twitter account, feel free to follow me. If you’re not on twitter, I hope you enjoy this selection of stories; links are provided so you can explore each one fully.

Here are this week’s favourites:

  • Could “healthy living vouchers” help promote healthy lifestyle choices? Matt Ridley, from the Wall Street Journal in his opinion piece “Free-Market Solutions for Overweight Americans“, suggests that vouchers which could be redeemed for gym workouts, vegetables, etc… would be beneficial to those who wish to lose weight. While I like the idea of providing incentives for making healthy choices instead of discouraging unhealthy habits, I believe that its important to highlight that this has the potential to be beneficial for all, not just individuals who are overweight as suggested by the article.
  • Imagine a junk food snack that provides 41 kcal per 100 grams, has a healthy dose of Vitamins A and C, and also boosts your fiber intake. Oh, and its unprocessed, has a satisfying crunch, and comes in orange, yellow, and sometimes purple. Too good to be true? Think again: How carrots became the new junk food
  • My colleague who blogs at Verdant Nation shared a link on twitter: Stairway to Health. This program, started in 2003, provides resources to workplaces to help encourage employees to take the stairs. Check out the point-of-decision posters, a great example of feedback to support behaviour change!
