Incorrect signage

Can you spot what's wrong with this picture?

One of the things about working in Human Factors is that you become sensitive to things that are different or wrong. Nowhere is this more apparent than in the area of labelling and signage, and not just in the workplace, but other places too. So when I recently stepped into an elevator and saw this sign, I did a double take.

Can you spot what’s odd or different about it?

    You are so right. Signs can be absolutely crazy. Especially the ones in elevators. Did you take the picture or did Dave?


      Dave and I were in the elevator together and he had his smartphone with him, so the photocredit is his. The elevator is in the Holiday Inn Express in Hull, UK. Such is the glamorous life of an ABB Human Factors Consultant :D
      I wrote a followup piece about why signs and other mental models are important in my 'other' blog which you can read at

      or just google 'Human Factors Blog', we're #1 on the list.
