ERRORS
A type I error,
Or a false positive,
As believing something is real
When it is not.
A type II error,
Or a false negative,
Is not believing something is real
When it is.
Believers in UFOs, alien abductions,
ESP, and psychic phenomena
Have committed a Type 1 Error in thinking:
They are believing a falsehood.
... It’s not that these folks
Are ignorant or uninformed;
They are intelligent but misinformed.
Their thinking has gone wrong.
In the search for truth
It could be that we ignore
Evidence of the truth,
By ‘neglect’,
In order not to be ‘duped’,
Or because it is not what we wish.
So, we believe a falsehood.
This is a type-1 error.
To compound this,
Sometimes we go on to believe
The opposite, regardless,
A type-2 error—and get duped anyway.
The terms Type I error (false positive)
And type II error (false negative)
Are used to describe possible errors
Made in a statistical decision process.
Type I: reject the null-hypothesis
When the null-hypothesis is true, and
Type II: fail to reject the null-hypothesis
When the null-hypothesis is false
We must be able to reduce the chance
Of rejecting a true hypothesis
To as low a value as desired;
And the test must be so devised
That it will reject the hypothesis tested
When it is likely to be false”
A type I error, or a false positive,
Is believing something is real when it is not.
