Supermarket shopping carts (trolleys) tend to have horizontal handles – would people buy more things if the handles were parallel – like a wheelbarrow? New research from City University of London and the University of Innsbruck suggest that the answer could be ‘yes’.
In an experimental study :
“supermarket shoppers purchased more products and spent more of their own money when shopping with a parallel-handle cart than with a standard horizontal handlebar.“
The reasons, say the researchers, may lie in the activation of a different set of arm muscles which push carts wihich have parallel handles.
