Years ago I went on a health & safety course, the instructor taught us some thing that has always stuck with me, it was how graphical information can be tested for honesty and that collected information will always follow a set formula.
It will either be a parimid (sp) with the largest figure at the bottom leading to the smallest figure at the top eg imagine the severity of injuries on a building site........ the largest number at the bottom of minor injuries leading to the top which is deaths of which there will be a small number. The figure make the shape of a parimid
Or it will be a bulge out shape with the smallest number at the top or bottom and the largest number in the middle.eg: people's amount exercise, the bottoms will be small of people who do no excercise, the middle will be large who do moderate excercise and the top small people who do a excessive exercise.
Hope this makes sense
Most collected information follows this formula, apart from this poll which is the exact opposite. the smallest figure is in the middle and the largest at the top and bottom of the earning scale.
In my opinion This poll is just people purposely giving the wrong answer for a laugh or just lying, does anyone really believe that there are 12 times more people earning the top figure than the one in the middle?
