The "identify the grid squares which contain a sign" type CAPTCHA isn't clear about whether you should be selecting all grid squares that contain mostly sign, or all grid squares that contain ANY of the sign. I imagine that particular one causes a fair discrepancy in what people select.
In fact I want to know what other people choose to do for those one. I'd like to guess that Hacker News types would disproportionately choose the latter option.
- manojlds 9y agoYeah I do any of the sign.
- bogomipz 9y agoInteresting, my assumption has been that it must reside mostly or entirely in the square. Now I'm wondering are the instruction intentionally vague?
- wruza 9y agoI think they shift selection grid from user to user, so they get a statistical outcome with a great precision of where the sign really is. If some data points stand out, they should be simply ignored.
- harshreality 9y agoA million times this. - Do the posts or supports of the signs count as part of the signs? - What if it's a sign but not a street sign? - If the camera is looking across a road, but the pavement isn't visible, does that image contain a road? I suspect humans are answering that differently, but it's not as bad as the sign one. - Storefronts. Sometimes I can't tell what I'm looking at. There's a building with lettering on it, but I can't tell whether it's a store much less a storefront. Google needs to add a tutorial for humans on how to answer those captchas, because there's not enough context for us to figure out what google really wants. If they'd dogfood this and require their employees to solve a captcha to login to their workstations, this problem would have been solved yesterday.
