Obviously there's a BBC dancer in the sh*t at the minute for this. In a lot of jobs making this kind of remark is your worst nightmare - I've come close a number of times. Now I was thinking, there's a good language-based reason why this happens. Your brain encodes language rules. Who comes from Afghanistan? Afghans. Who comes from Turkmenistan? Turkmen. Who comes from Kazakhstan? Kazakhs. Who comes from Uzbekistan? Uzbeks. Who comes from Tajikistan? Tajiks. So now, quickly, without thinking about it, tell me who comes from Pakistan?
