Verifying Information

What does it mean to verify information? How do you know what you know?

Take the following challenge, for example, and post your proof in the comment section.

What do the following people have in common?

  • Avril Lavigne
  • Celine Dion
  • Alanis Morissette
  • Justin Bieber
  • Barenaked Ladies
  • Nelly Furtado
  • Nickleback

Pretty easy, right? Now prove it. (a task that may prove not so easy…)

Incentives matter, and please don’t spit in my food!

I was at a local quick subway-style food place, and had to use the restrooms while they finished my to-go order, when I started thinking about incentives. I used to teach economics, to I feel I understand some things about incentives, from an economic perspective, and how it relates to people’s behavior.

“What if they spit in my food?”

Basic economics suggests that they won’t, beacause they’ll want me to come back, right? But, who most likely works in a place like this? Not necessarily the long-term type, right? In a regular scenario, employees are incetivized to perform, to make more money, keep their jobs, etc. But, not employees that are there for the short term!

So, hypothetically, an employee who works for the short-term, has no incentive to perform, and hence can essentially perform however they want. Unless they want a reference, I suppose.

So, the next time I’m in one of these places, I’ll definitely think twice about leaving the service counter while they prepare my food, since I value “clean” sandwiches.

However, I still know nothing about what took place five minutes before I entered the establishment, or if the employees even bother washing their hands. The worst is when they take cash payment, using the same gloves they use to prepare my food. The glove keeps their hands clean, not necessarily my food. What kind of solution is that?

Afterschool Film: ‘Restrepo’ – Comments

What did you think of the film? What comments, reflections, suggestions, and insights do you have?

For history students, answer this question as well: What are some similarities between what you know about Vietnam, and what you saw in ‘Restrepo’?

For economics students, answer this question as well: What are some economic effects of these guys (from ‘Restrepo’) coming back into society?

Road Signs: What they actually mean!

Driving to work this morning, it struck me how inaccurate some of the road signs I see are. Of course, their job is to warn us drivers of dangers ahead, speed limits, and work areas, but oftentimes, what you see on the sign and what appears in reality don’t match. Here is one quick example:

Stated:  Warning – a difference in heights between road surfaces ahead!

Actual:  Warning – a device that will seek to destroy your tires, especially if you’re traveling faster than 10 MPH.
