Senator Grayton is a fictional character, made up for this comic, which is unusual for xkcd, which typically uses real-world references.

The issues that Grayton supports:
  
*Tax Breaks to Drunk Drivers - Grayton proposed to give money back on their taxes for people who have been convicted of a DUI or DWI. Driving Under the Influence or Driving While Intoxicated
+
*Tax Breaks to Drunk Drivers: Grayton proposes giving those who have been convicted of a {{w|DUI}} or DWI (i.e. Driving Under the Influence or Driving While Intoxicated) money back on their taxes, when those infractions are typically severely penalized, as drunk driving has resulted in numerous deaths.
*Predator Drones and the {{w|Christmas controversy|War on Christmas}} - The War on Christmas is a not a real war, it is simply non-Christians who believe that {{w|Christians}} are trying to get rid of Christmas trees, Christmas music and the endless barrage of Christmas-themed nonsense we get from Thanksgiving to Christmas. I don't know how his support would go down if he supported unmanned Predator Drones to destroy people who hate Christmas, knowing America. (Jokes!)
+
*{{w|Predator Drones}} and the {{w|Christmas controversy|War on Christmas}}: The War on {{w|Christmas}} is not a real war; it is simply the perception by some {{w|Christian}}s that non-Christians are trying to replace traditional Christmas imagery with more inclusive and generic holiday customs. No politicians have explicitly announced their support of the "War on Christmas," and the idea that one would not only do so, but would also want to use drones—ostensibly to harm or possibly kill people—in the effort is an absurd exaggeration of a relatively harmless culture war.
*College Scholarships to Sexually Active Teens - Not sure how they would test for this on the scholarship application, but it is funny nonetheless.
 
*Illegal Immigrants Who Murder - This is an argument for immigration, but only if they make "room" and possibly an open job for themselves by getting rid of another person.  This one is pretty evil.
 
*Income Tax Based on Penis Size - Wow, this one would never pass!
 
  
On To the Names:
+
The term {{w|percentage point}} is used to overcome an abiguity when comparing two percentages. Assuming an original sample of 1,000,000 people, where 20% approve of Senator Grayton. However, it could also refer to a lead of a 20% point margin.
  
*{{w|Tracy Morgan}} is an actor in the TV Show {{w|30 Rock}}, who plays {{w|Tracy Jordan}}, he is known for his outlandish statements on politics and everything else in the world. He has been reprimanded for controversial comments on homosexuals and {{w|Sarah Palin}} (in separate incidents).
+
'''Reduction of a stated number by a percentage'''
*{{w|Josh Wilkes Booth}} is the person who assassinated {{w|Abraham Lincoln}}.  He was a sympathizer with the {{w|Confederate}} cause and was for slavery and all its trappings.
+
:When the original value is given as a number, there is no ambiguity. In the statement below the only possible conclusion is that now only 162,000 people approve of Grayton.
*{{w|Time Cube}} Guy is Gene Ray, also known as Otis E. Ray.  He has a website known as Time Cube (Thanks Wikipedia) where he sets out his personal model of reality, which he calls Time Cube. He suggests that all of modern physics is wrong, in addition to claiming religion to be evil, specifically Christianity, and the idea of family is poisoning children.
+
:''Previously 200,000 people approved of Senator Grayton, and then his approval rating dropped by 19%.''
  
Ok, finally to the numbers:
+
'''Reduction of a percentage by a percentage'''
 +
:When the original approval rating is given as a percentage (20% in the comic), then a reduction of 19% has two possible meanings:
 +
:1) Of the 20% who previously approved (200,000 people), 19% no longer approve. In this case the result is 162,000 as in the above example.
 +
:2) Compared to the original results, 19% fewer of the entire original sample of 1 million people approve. In this case only 1% of the original 1 million approve, equal to 10,000 people.
  
If his polling is at 20% and drops by 19%, without specifying percentage points, that means that his support has only dropped 3.8 percentage points, because 19% of 20% is only 3.8%. That would mean after all his outrageous statements, his support dropped from 20% to 16.2%. However, if they had said his 20% polling dropped 19 percentage points, that would mean his support has dropped to 1%. Therefore, the distinction is important.
+
If using the second method of comparing percentages, the approvals rating should be described as having dropped by 19 percentage points. In reality, the distinction between the two methods is often overlooked, leading to confusion.
 +
 
 +
The caption's issue with "percentage" versus "percentage points" is that if Grayton's 20% approval rating drops by 19%, that means that his support has only dropped 3.8 percentage points since 19% of 20% is only 3.8%. That would mean that even after all his outrageous statements, his support dropped only from 20% to 16.2%. However, if the news reports that his 20% approval rating dropped 19 ''percentage points'', that means his support has dropped to 1%, which appears to be more accurate given Grayton's egregious policy decisions and the description of his campaign as having "imploded."
 +

The punchline to all this is that Randall is more bothered by the "percent" ambiguity than by Grayton's appalling policy plans.

Explanation[edit]

Senator Grayton is a fictional character, made up for this comic, which is unusual for xkcd, which typically uses real-world references.

The issues that Grayton supports:

  • Tax Breaks to Drunk Drivers: Grayton proposes giving those who have been convicted of a DUI or DWI (i.e. Driving Under the Influence or Driving While Intoxicated) money back on their taxes, when those infractions are typically severely penalized, as drunk driving has resulted in numerous deaths.
  • Predator Drones and the War on Christmas: The War on Christmas is not a real war; it is simply the perception by some Christians that non-Christians are trying to replace traditional Christmas imagery with more inclusive and generic holiday customs. No politicians have explicitly announced their support of the "War on Christmas," and the idea that one would not only do so, but would also want to use drones—ostensibly to harm or possibly kill people—in the effort is an absurd exaggeration of a relatively harmless culture war.

The term percentage point is used to overcome an abiguity when comparing two percentages. Assuming an original sample of 1,000,000 people, where 20% approve of Senator Grayton. However, it could also refer to a lead of a 20% point margin.

Reduction of a stated number by a percentage

When the original value is given as a number, there is no ambiguity. In the statement below the only possible conclusion is that now only 162,000 people approve of Grayton.
Previously 200,000 people approved of Senator Grayton, and then his approval rating dropped by 19%.

Reduction of a percentage by a percentage

When the original approval rating is given as a percentage (20% in the comic), then a reduction of 19% has two possible meanings:
1) Of the 20% who previously approved (200,000 people), 19% no longer approve. In this case the result is 162,000 as in the above example.
2) Compared to the original results, 19% fewer of the entire original sample of 1 million people approve. In this case only 1% of the original 1 million approve, equal to 10,000 people.

If using the second method of comparing percentages, the approvals rating should be described as having dropped by 19 percentage points. In reality, the distinction between the two methods is often overlooked, leading to confusion.

The caption's issue with "percentage" versus "percentage points" is that if Grayton's 20% approval rating drops by 19%, that means that his support has only dropped 3.8 percentage points since 19% of 20% is only 3.8%. That would mean that even after all his outrageous statements, his support dropped only from 20% to 16.2%. However, if the news reports that his 20% approval rating dropped 19 percentage points, that means his support has dropped to 1%, which appears to be more accurate given Grayton's egregious policy decisions and the description of his campaign as having "imploded."

The punchline to all this is that Randall is more bothered by the "percent" ambiguity than by Grayton's appalling policy plans.

  • John Wilkes Booth is the person who assassinated Abraham Lincoln. He was a Confederate sympathizer and supported slavery.
  • "The Time Cube Guy" would be Gene Ray, also known as Otis E. Ray.

  • College Scholarships to Sexually Active Teens: Many people think adolescents should not engage in sexual activity, let alone be encouraged to do so by college scholarships. This is the opposite of abstinence programs, which encourage teens not to be sexually active until marriage.

  • Graduated income tax based on penis size: Many men are sensitive about their penis size and would probably consider the measurement of their penises for tax assessment purposes an enormous embarrassment and invasion of privacy. Even the scenario in which those with relatively smaller penises would be levied less tax than those with larger penises would probably not be sufficient for them to accept this policy, and even if they did, those with larger penises would probably consider this policy to be unfair.

Discussion

Our study shows that only 5% of people know the difference between percentages and percentage points. This is 50% lower than in 2009. --DiEvAl (talk) 06:30, 16 August 2013 (UTC)

Actually, penis size based tax is a brilliant idea. You only have to tax proportional to size, and, now comes the utterly clever part, let the male citizen self-declare his penis size. Voila, tax flow will always be higher than planned. 108.162.230.89 17:58, 10 September 2014 (UTC)

I am glad that under this system my tax burden would be unashamedly miniscule! Which is probably something no one wanted to know! -Pennpenn 162.158.2.221 06:15, 15 June 2015 (UTC)
  You've overlooked the fact that there is no reference to whether the measurement would be plus or minus and where the measurement would be taken. The tax could be on those with small (or no) penises. And to do it that way would make sure the tax included both those with and those without a penis.

Perhaps age could be a factor and of course shrinkage must be taken into consideration. Jakee308 (talk) 11:21, 16 June 2015 (UTC)

I was actually 108.162.230.89's idea, not what's in the comic. That concept was self declaring, so no measurement, and proportional, so "larger size = higher tax". -Pennpenn 162.158.2.221 23:54, 18 June 2015 (UTC)
