As we know, there are known knowns. There are things we know we know. We also know there are known unknowns. That is to say, we know there are some things we do not know. But there are also unknown unknowns: the ones we don't know we don't know. —Feb. 12, 2002, Department of Defense news briefing
Laying the Groundwork for Thinking about Liberty ~ or ~ One misguided zealot can wreak more havoc than a roomful of idiots.

Misconceptions Are the Enemy (a real conversation) As wages rise, more people enter the labor market. Cool.
Misconceptions Are the Enemy As wages rise, firms cut back on hiring. Got it.
Misconceptions Are the Enemy Therefore, price floors create surpluses. No problem.

How Do We Dispel Misconceptions? Data Demonstrations
Workers Firms Find a firm willing to hire you at whatever price you can negotiate. Goal: Get the highest wage you can. Hire workers at whatever price you can negotiate. Goal: Maximize profit.
Firms Each firm gets a chart like this. The chart is the firm’s factory. Each unit the firm produces is automatically sold for $4.
Suppose you can negotiate a price of $10 per worker. All the workers will be hired 0% unemployment.
Now, impose a minimum wage of $15 per worker. Only half of the workers will be hired 50% unemployment.
This demonstration can be done in 20 minutes and students immediately “get” two important lessons: • Minimum wage causes unemployment. • Left alone, firms will not pay zero.
Demonstration and data remove misconceptions, opening the mind to more knowledge.
Inoculate Against Misconceptions Economic misconceptions are usually the result of pride and prejudice.
Prejudice • Humans who work in the private sector are greedy. • Humans who work in the public sector are altruistic.
Truth • The same humans with the same strengths, failings, and desires occupy both sectors.
Schizophrenic Voters • The same people you claim are selfish in the marketplace you also claim are selfless in the voting booth.
Addict Voters • People want to be forced to do the right thing! Save us!
Pride • Economic truths are opinion.
Truth • The whole point of economic theory is to describe the real world. • Disconnects arise not from a failure of economics but from a lack of understanding of what economics is telling us.
Pride • Unwillingness to admit limitations.
Truth • It is impossible for an economy to provide everything that everyone wants. • Corollary: A majority vote does not bestow magical powers to circumvent limitations.
What We Need To Do Dispel misconceptions with data and demonstration. Inoculate by warning against pride and prejudice.
