Update on October 08, 2012
It's October 8th, and what have we learned so far?
The option to never give my child any vaccines is polling at 47% of 786 votes. If this were a contest you'd have to say that the NO! NO! NO! vote was winning.
But this isn't a contest. It is an experiment about what happens on the internet when you ask a question like this. Clearly the number of people in the population who are opposed to vaccination is a small fraction of 47% - it's certainly less than 5% and probably a lot less. But this isn't a scientific poll. All responders are self selected. People who are opposed to vaccination have shown up completely out of proportion to their actual numbers. This suggests to me that they are more worked up about the issue, more passionate, and more willing to take action than other segments of the population. It also suggests that they are more organised, at least insofar as they talk to one another and suggest to fellow antivaxxers that they take this poll and make a comment or two.
This is exactly the outcome I should have predicted. The anti-vaccine crowd is louder and more strident than the pro-vaccine crowd. Perhaps this is because they feel that they are a minority and are discriminated against. Perhaps they feel that since they have seen through the massive deception orchestrated by the pharmaceutical industry, the medical industries, most science and every government on Earth, they need to get the word out. I don't know. I just know that they have swarmed all over this poll.
I thought for a while that pro-vaccine groups would take on the challenge and change the numbers, but this hasn't happened, at least not yet. Soon everyone will lose interest in this, and I'll let the poll die. Until then it will be interesting to see where it all goes.
