This Week’s Poll Closed Due to Self-Selection Bias
I’ve never closed a weekly poll before, I’ve always let them run Sunday to Sunday. Â But on Monday I decided to close this week’s poll. Why? When the number of votes after 36 hours exceeded the typical number of votes for an entire week it was very clear I was not getting the perspective of my usual reader. The poll had zero value with such a highly biased sample:
Self-selection bias, which is possible whenever the group of people being studied has any form of control over whether to participate. Participants’ decision to participate may be correlated with traits that affect the study, making the participants a non-representative sample. For example, people who have strong opinions or substantial knowledge may be more willing to spend time answering a survey than those who do not. Another example is online and phone-in polls, which are biased samples because the respondents are self-selected. Those individuals who are highly motivated to respond, typically individuals who have strong opinions, are overrepresented, and individuals that are indifferent or apathetic are less likely to respond. This often leads to a polarization of responses with extreme perspectives being given a disproportionate weight in the summary. As a result, these types of polls are regarded as unscientific.
There have been many weekly polls in the last couple of years where the results differed from my personal viewpoint, but that was the viewpoints of the readers.
That said, here are the results from the first 36 hours of the poll:
- Should be repealed 47 [40.87%]
- Don’t like the law, but I do like having more smoke-free places 10 [8.7%]
- So glad we are finally a smoke-free city! 23 [20%]
- Great, but we need to remove exemptions so all employers are smoke-free 33 [28.7%]
- Other: 2 [1.74%]
- unsure/no opinion 0 [0%]
Those who want to repeal the ban make up the single biggest group, but nearly half like the law (48%). Â Here were the two other answers:
- i like it, leave smokers some places tho
- In America, smoking cigarettes is freedom. Stop infringing on my freedom!
Ah yes freedom! The freedom to make others smell your addictive habit. The freedom to make anyplace smell like an ashtray simply from the toxins contained in your clothing. The freedom to fill the bus or light rail train car with smoke. The freedom to be completely inconsiderate of others around you.
Most likely I will never do a poll about smoking again.

None of your polls could be guaranteed to be scientific. You removed this one because you disagreed with the fervent self-selectors?

Steve, next ask that the poll be limited to regular readers of your blog.

Bill, next time maybe you can take a few days out of your life to stop searching for any post having to do with smoking in St. Louis. Your campaign is slowly fading, sort of like your lungs (and ours as long as their smoking in public spaces).
I am involved with lots of local freedom and property rights issues, not just the rights of bar owners.

We live in a socieity that is all about me. Few have consideration of others anymore. You should read the stink on the no-cell ban in Werhnberg theaters…something others have been doing for months (thank you St. Louis Cinemas). Why can’t people realize that OTHER PEOPLE share this world.  You want to smoke….do it at home, in the car or away from others and STOP DROPPING BUTTS ON THE GROUND OR OUT THE WINDOW. Nature is not your f—–g ashtray.

I don’t think anyone voted under a fake name or more than once.
How do you actually know this unless you took part in orchestrating the voting?
Ooooh. Now this is getting interesting!
…or not. It’s a poll. Get over it. Any week on any blog, someone with access to a computer lab and a pathetic extra half hour of time could overload a blog poll.
For the record, I find smoking gross, but I also find “removing a poll due to self selection bias” due to the author/poll originator’s own bias to be perhaps more gross.
Reinstate this poll now so the 3 people who care can have their say.
