Oh yeh I do that too. If I am umming and ahhing about pictures and then I find out one has 20,000 votes, I will choose the other just so that they can see they were voted for. I really don't like landslides because I honestly do not believe that the competitions (that I have seen) are so unbalanced that one picture is so far above the others. It would be fascinating to do an exit poll (in theory, in practice who could be bothered) asking questions like "have you been there", "what were your top 4 choices", "Are you an amateur photographer?" and of course the very heated "do you recognise the photographer", it would always be interesting to see a comparison of voters to winner and voters to photographer to see parallels... and I do not say any of this in an accusatory sense.
My theory is that correlation would be due to several factors:
1. Having been to the location (because I know I would vote for NZ hikes ahead of most others, how could I not).
2. A leaning toward the style of a particular photography (not to say they realise that it is the same photographer... but I wonder how many people lean toward one photographer without realising it).
I would be very curious as to whether the second point applied to a consistent group of people... ie is there a large proportion of people that consistently vote for the winner (without any knowledge of the way others have voted, or of the photographer).
I hope this all comes across with fascination and no other ill intent, because I do believe the landslides are unusual but I don't believe it is simply akin to getting all your FB friends to vote for your awful picture so you can win a competition on some facebook page (I hope you are all familiar enough with facebook to understand the facebook photo comp bias). I was actually a math teacher in the past, and I recall that while at university I had a strong desire to sit outside the McDonalds drive-through and compare burger order with the colour of the car to see if there was a correlation.
Also, enjoying the theory of this discussion as it applies to any photo comp of this type... not actually implying anybody would or should actually do this. Who has that sort of time? Too busy planning for the next walk.
