A right wing nut was screaming at me recently, (something they often do). He 
blasted out that the disparity in school funding was completely meaningless. 
His general tactic, besides the screaming, was what I call the outlier 
deception. This is used a great deal lately in spin and warrants some 
discussion.

When a researcher or policy maker looks at a large sample, there may be 
individual data points, which lie far outside the pattern indicated by the 
majority of data. These outliers may mean many things depending on the 
circumstances. One thing that is important is that it is honestly reported as 
an outlier.

The outlier deception must reject the overwhelming pattern detected in the 
sample. The deceiver then replaces that data and pattern by handpicking 
outliers to build a dishonest case. The person makes the claim that the 
outliers actually represent the pattern visible from the complete sample. 

Schools: I mentioned, to the screamer, the graduation gap between urban and 
suburban areas detected in a national research project. Here in PA, we have 
long known that there is a tremendous public education funding gap between 
Phila. and wealthier suburban areas. We also have known that we have a poor 
graduation rate in Phila, and this has been blamed on lazy teachers and 
corruption/ waste by the administrators of poor districts. 

Low and behold, the very same problem that Phila public education faces repeats 
itself across the country. We need to also look at per pupil spending to see 
the exact picture, but I think it is generally known that the funding gap and 
suburban/urban income divide are national realities.

If someone searches the outliers, that person will find a wealthy district that 
performs poorly and some small heroic urban district that performs as well as 
schools in the civilized democracies of the world. (These would be important 
outliers for further study and discussion.) But the outliers will not indicate 
the pattern that must be important for policy makers. 

After thinking about it, this outlier deception is used a great deal by 
corporate media. It makes sense that this screamer also relied on this tactic. 
Educated people, who have not been co-opted or don't have a conflict of 
interest, should see through this and reject the argument every time. They 
should point out that this is a very dishonest trick to employ so that everyone 
can consider the overall integrity of the presentation being offered to defend 
a policy decision.

Thanks for your consideration,

Glenn
