I came across some interesting articles on how urban legends are born and kept alive. This is especially true of readers who skim an academic discipline, for example, by reading Malcom Gladwell, and don’t put in the effort to stay updated. And just how the secret of advertising is repetition, repetition, repetition, some “truths” stick around long after they have been debunked simply because they get repeated often enough.<\/p>\n
Made famous by Outliers<\/em> by Malcolm Gladwell, the 2008 book’s “10,000-hour rule” turned most “Soccer Moms” into “Tiger Moms.” However, we now know that Gladwell’s book mistook the average<\/em> of 10,000 hours that experts took to master a skill with the total<\/em> they required. Plenty of studies suggest that aside from practice hours, individual differences help explain success: from socioeconomics to coaching to I.Q.<\/p>\n However, they myth lives on as more and more people read the book and not the errata.<\/p>\n Source:<\/strong> National Geographic<\/a><\/p>\n In 1981<\/strong> and again in 1995<\/strong>: In 2011<\/strong>: So spinach is<\/em> useless as a source of iron. But not because of a measurement error. Try to get your mom to believe it.<\/p>\nIs Spinach a good source of iron?<\/h3>\n
\nThe myth from the 1930s that spinach is a rich source of iron was due to misleading information in the original publication: a malpositioned decimal point gave a 10-fold overestimate of iron content. <\/p>\n
\nThe story that the iron content of spinach was a myth based on a misplaced decimal point is itself a myth. Spinach has a lot of iron, just like other green vegetables, but it is unavailable for absorption. <\/p>\n
