I have no science to add, but do have an anecdote:</div><div dir="ltr" class="gmail_attr"><br></div><div dir="ltr" class="gmail_attr">My grandfather (in the UK) was also exceptionally good at finding four leaved clovers, and had pages and pages of dried and pressed examples that he'd found over the years (a couple of hundred, including some five-leaf clovers). He taught me his strategy when I was small, which consisted of:</div><div dir="ltr" class="gmail_attr"><br></div><div dir="ltr" class="gmail_attr">1. "Remember that there is no luck involved, most people just don't have the patience to look." </div><div dir="ltr" class="gmail_attr">2. Start by passing your eyes lightly over a patch of clover, and noticing any place where your eyes pause or something seems "different", then carefully examine those places (which is perhaps using preattentive vision to detect regions with slight differences in texture statistics). </div><div dir="ltr" class="gmail_attr">3. Once you find one, trace it back to the roots and see if the plant has other mutant leaves (cheating, or just pragmatic?) </div><div dir="ltr" class="gmail_attr"><br></div><div dir="ltr" class="gmail_attr">I've practiced his advice over the years, and found that many large patches of clover do indeed contain four leaved instances. So, my first questions would be whether the German family has some similar strategic lore that they have passed down, and whether they simply engage in the (pleasant) pastime of searching clover patches more often than your average person.... </div><div dir="ltr" class="gmail_attr"><br></div><div dir="ltr" class="gmail_attr">Best, </div><div dir="ltr" class="gmail_attr">Kate Storrs </div></div><div dir="auto"><br></div><div dir="auto">_______________</div><div dir="auto"><br></div><div dir="auto">Dr Katherine Storrs </div><div dir="auto">Postdoctoral researcher,</div><div dir="auto">Abteilung Allgemeine Psychologie</div><div dir="auto">Justus-Liebig-Universität, Otto-Behaghel-Str. 10, 35394 Giessen </div><div dir="auto"><a href="http://www.katestorrs.com">www.katestorrs.com</a></div><div class="gmail_quote" dir="auto"><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
