Most of the time, the wind will have caused the sound, but &#8220;if a group of lions is coming there\u2019s a huge benefit to not being around,&#8221; Foster says.<\/p>\n<p>Foster and colleague Hanna Kokko, of the University of Helsinki, Finland, sought to determine exactly when such potentially false connections pay off.<br \/>\nSimplified behaviour<\/p>\n<p>Rather than author just-so stories for every possible superstition \u2013 from lucky rabbit&#8217;s feet to Mayan numerology \u2013 Foster and Kokko worked with mathematical language and a simple definition for superstition that includes animals and even bacteria.<\/p>\n<p>The pair modelled the situations in which superstition is adaptive. As long as the cost of believing a superstition is less than the cost of missing a real association, superstitious beliefs will be favoured.<\/p><\/blockquote>\n<p>Read the <a href=\"http:\/\/www.newscientist.com\/channel\/being-human\/dn14694-superstitions-evolved-to-help-us-survive.html\">full article<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Superstitions evolved to help us survive according to this New Scientist article.
