Fence Tape and Cow Brains

[..] Rather than building costly and unwieldy fences, ranchers will leave one section of the fence unbuilt and instead have a line of tape extending across the gap at the cows’ eye level. The cows, not understanding that this tape would be easily broken by the pressure of their applied momentum, choose never to even test the barrier, figuring in their cow-brains that this limitation is just as solid and indefatigable as all the rest of the fence, which they’d given up trying to break years before.
