We all like to think our powers of observation are on point, but an infuriating new test might just prove you wrong.

Change blindness is a subconscious blind spot which causes us to completely miss subtle changes in something even if it happens in front of our eyes.

Experts have been looking into this for twenty years, and have now come up with a fascinating interactive test which shows just how observational you really are, reports Daily Mail.


Perhaps surprisingly, men came out above women in the test, while an international test showed that Germany came out on top, and a nationwide survey saw Glasgow come out in first place, and London in fifth.

The interactive brain teaser devised by retailer Lenstore UK tests your attention to detail by showing you five pairs seemingly identical images that alternate back and forth.

In between each pair, you are shown a grey screen for just a fraction of a second - after which one small detail is altered before switching back to the original image.

You have just 45 seconds to identify the change by clicking on it, and at the end of it you are given a score out of five.

If you score five out of five you have the highest level of perception possible, but if you score anything below three you suffer with change blindness.

And a result of anything below two means you're "severely affected by the phenomena".

Experts tracked all 22,000 responses from all round the world so far, and discovered that men had stronger observational skills than women.

While men scored on average of 2.7 correct answers out of five, women scored a slightly lower average of 2.2.

Meanwhile Glasgow topped the list of the cities with the sharpest observation skills in the United Kingdom with 2.28, while people in Dublin scored just 1.87.

And an international survey proved Germany is the most perceptive nation on the planet with a collective average of 2.21, while the UK landed third with 2.06 and Australia came last with 1.07.
