Policy debates often involve "experts". But what is
an expert? See this
interesting article from the USA Today (7/18/05). |

Read this essay about
why science matters and why it is a way of life from the NY Times
(6/1/08) |

According the
World Health Organization (WHO), cell phones can cause brain
tumors and the press seems to agree (See
this collection of news reports of the WHO finding). But
do they?
See this critique of their finding and a
news account from 2
weeks prior to the WHO meeting that said the researchers
concluded that there was no clear link? Also be sure to read
page 5 of the
WHO press release that describes what a group 2b finding is and
think about what evidence is needed to reach that conclusion.
A statistical correlation is one thing but what about the
substantive significance of their finding. Understanding that
would require first understanding the baseline risk of getting any
type of brain cancer in the first place (See
NIH fact sheet) and then understanding that gliomas are a
subset of the various types of brain cancer and are relatively rare
amount the different types. Moreover, if cell phones did cause
cancer, shouldn't there be some detectable increase in brain tumors
considering they have been in widespread use for more than a decade?
There does not appear to be much evidence in the medical literature
that this is the case. |

Read this thoughtful essay about the importance of language for
managers and policy analysts from a recent issue of the PA Times
(Nov/Dec 2010). |

"Poverty" is an excellent example of problem definition
and the role that changing values play. See
this chart and an
article from the
Washington Post (9/10) on rising poverty rates. This chart
from the New York Times also illustrates a
variety of perspectives on
poverty and unemployment around the country (9/11). For an
alternative perspective, see this article from
National Review
online and a report prepared by the
Heritage Foundation (July 2011). |
 |
Is the growing national debt a problem? See this
recent article from the LA
Times (8/23/11). See this figure
for the growth in the debt ceiling since 1980. See
this chart on increased government spending. Are entitlements
to blame or are big increases in government spending.
See this interesting
perspective (8/11). Is it because the rich are not
paying there fair share in taxes? See this article exploring
how much could be raised by taxing
the "rich" (8/11). |
 |
Policy analysts often have to think counter-intuitively
because the world doesn't always work the way we think it does.
Give some thought to the problems identified in these articles.
Why are ICU
deaths higher on the weekend (7/10)? Why do
heavy
drinkers outlive non-drinkers (8/10)? Why is
weight loss toxic
(9/10)? Are we doomed to repeat the collapse of the housing market
in the life
insurance industry by allowing the same risky investments (NY Times
9/09)? Is the changing
nature of
work responsible for increasing obesity (NYT - 5/11)? Why
do Black
men live longer in prison (Reuters 7/11)? |
 |
Is it actually safer to be modestly overweight than
underweight? See this report in the JAMA on Obesity
and Death (2005) and a related article about
CDC linking risk of
death to obesity (2005). |
 |
While data and numbers are important, communicating these
results effectively using tools like PowerPoint is critically important.
See this interesting article from Government Executive about
how PowerPoint can be
the enemy of thought (9/1/04). |
 |
While numbers and data are important, it is also
important to know where these numbers come from and what they mean.
See this
interesting article about the fudging of crime statistics (2/10) in
New York. It is also important to realize if you are looking for
something you never looked for before, you may find more of it but that
doesn't mean there really is more of it. See this interesting
article from the USA
Today on Mercury in the water (8/04) |
 |
It always important for policy analysts to remember that
people (and politicians) are often bad judges of risk. See this
interesting article from the USA
Today (8/06) on risk. Yet it is common to read articles
highlighting dangers that play on our inability to understand risk.
Are bear attacks a big danger
(La Times - 8 /11)? Are
playgrounds too safe (NYT
7/11)? |
 |
Of course, sometimes there are extremely
unlucky individuals. See this interesting article about a man
whose house has
been struck by a meteorite 6 times (7/10). If you lived next
door to him would your chances of being hit by a meteorite increase or
decrease? |
 |
However, sometimes your read statistics that just don't
make sense. How could it be more likely to be hit by a piece of a
satellite (estimated at 1 in 3,200) (Download
article) than
by lightning
in your lifetime (1 in 10,000). I'm betting whomever did the
math to produce the estimate reported in this article failed their
statistics class. Although I still wouldn't want to live next door
to the man reported in the previous bullet when the satellite crashed to
earth. |

Sometimes efforts to solve one problem make other
problems worse. See this
interesting article from the USA Today on the problems related to
growing ethanol use (8/08). Similarly, the policies
implemented through no child left behind have led to wide spread
instances of teacher cheating. See this
USA Today investigative report: Testing
the System (Mar. '11), this set of
articles on a widespread
scandal in Atlanta as examples (7/11), and this story on
problems in South Carolina (2008) |

Hans Rosling gives
brilliant insight into the world’s explosively changing population, in
its physical, economic and political health. To say nothing about his
basic mission of teaching the use of statistical methodology.
