I work with colour a lot (theory, psychology, application, etc) and some years ago remember reading a piece in the BMJ about a medical research project related to colour impairment... I feel sure that the piece said that around 30% of males are either colour 'blind' or have some level colour impairment... I can't for the life of me find any evidence of this study online, so maybe there is new evidence that that takes the % back down to one in ten males... anyone know any thing about this?

Top left might be a 5 and 8?...

Top right defo 18...

Bottom left, nae chance...

Bottom right 1 and 7 or maybe 2?...


On the subject of lefties, there was a boy at my school who was naturally left handed, and he reckoned a doctor said he had developed a stammer because his parents tried to get him to use his right hand/foot when he was younger!..

BBW, I too have been tempted but saw the effects and read too much and saw too many photos. I drew my own conclusions and feel nightmares like that should be left in the past, if possible.


Is the diagram not 58, 18, E and 17?


Agreed Red Devil, never try to change the hand/foot that children use. I think it confuses them.

That happened to my grand-dad. I'm not sure what year he was born, but some time around the turn of the century. I understand that teachers would tie his left hand to his side. Anyway, he stammered all his life because of it, but had a lovely tenor singing voice, without stammer.


Edited to say - sorry for going (and remaining) off topic - I have never chewed gum!

If the first answer is "8" then I got the first two only.


The second, I assume is "10" no idea about the 3rd or 4th one.

    • It was normal cyclists, in rush hour traffic, in the dark, in the rain. Just really want people to realise it’s that time of year even more careful and to get kitted out.
    • The other consideration is that users of Lime bikes and similar, plus younger pedal cyclists, probably don't view themselves as 'cyclists' as such and so don't get kitted out or even consider that they need to. I also agree that earlier nights are another factor for the casual or hire bike user more used to cycling in the summer. I don't think I have ever seen a hire bike or scooter user wearing a helmet or reflective gear- presumably that is because the bike is just viewed as a transport tool for short term use and users do not want to be encumbered by any of the safety gear? Before anyone jumps on me for anecdotal evidence and speculation, this is just what I have seen round here, there may be hordes of similar users elsewhere that are kitted out.
    • Well apolitical if that is an OK word for you.  Sorry if my choice of words was incorrect.  But on my original point if it wasn't for the Telegraph dragging this up, and yes they do have an agenda, an no they are not apolitical/impartial whatever, we;d be none the wiser. But as it made no difference to Trump's election campaign that why would he have a case in the American courts? Irrespective of the rights and wrongs of the programme
