In science and statistical analysis it is called "Testing the Null Hypothesis." As described in the 1930s by a statistician named Ronald Fischer, during an experiment, when looking at observed data after an event or testing the use of some treatment on a patient, the null hypothesis is the theory the change in data is unrelated to the event, or that the treatment used had no positive or negative effect on the subject.
When given the choice of accepting or rejecting the Patient Protection and Affordable Care Act (PPACA) (or Obamacare)'s next big action step of expanding Medicaid to cover almost 1.2 million additional Floridian citizens, our state legislature decided to try some experiments instead.
One of the main concerns in Tallahassee, mainly among the Republican legislators, was over having to accept almost $51 Billion dollars from the federal government while offering the Medicaid health plan to families and individuals under 138 percent of the Federal Poverty Line (FPL). In Texas, Gov. Rick Perry called the federal funds "bribery" (Since when do politicians have to be bribed to do the right thing?) Here in Florida, legislators have offered reasons including everything from becoming increasingly "addicted to federal money" to fear that the U.S. government will default on their promise to the states, even though they have never failed in the past to pay their 53 percent match to our 47 percent funding of Medicaid since its inception in 1965.
