APAD: Lies, damn lies, and statistics.
This expression is generally used in order to cast doubt on statistics produced
by somebody a person does not agree with, or to describe how statistics can be
manipulated to support almost any position.
-------------------------------------------------------------------------------
This was attributed by Mark Twain to Benjamin Disraeli (1804-1881): "There are
three kinds of lies: lies, damned lies, and statistics." It's not clear how much
research either did.
Of course, it's humans instead of statistics to blame as practioners, for
expediency (read profit), willfully ignore rare but high-impact events, black
swans a la Nassim Taleb. If the facts do not fit the theory, change the facts.
Models are built, papers published, and text books written, all based on flawed
data.
The job for the rest of us is to try to stay a non-sucker.
