This is in part, as Wheelan explains, because \u201cnegative findings\u201d don&#8217;t make for attention-grabbing headlines. For example, people might not go out of their way to read a paper entitled \u201cWearing Skinny Jeans Has No Impact On Your Health.\u201d&nbsp;<\/p>\n\n\n\n<p>People are more interested in attention-grabbing headlines, such as a hypothetical: \u201cAre Your Skinny Jeans Killing You? Research Finds Link Between Skinny Jeans and Risk of Heart Attack!\u201d&nbsp;<\/p>\n\n\n\n<p>Wheelan explains that publication bias can lead to misconceptions and inflated confidence in research findings because people never get to see corresponding studies that might negate or temper published research results. For example, suppose a hypothetical study found a small positive correlation between owning a dog and lower rates of a certain type of cancer. In that case, people might rush to adopt a dog without ever knowing that five other studies found no such link.<\/p>\n\n\n\n<p>To combat publication bias, Wheelan explains that medical journals may enforce a policy that all studies on a particular research question be reported, not just the positive ones.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Positive Headlines Grab Public Attention<\/strong><\/h3>\n\n\n\n<p>Even when negative research findings do find their way to publication, they can be overshadowed by positive findings even if they present more reliable data.<br><br>For example, <a href=\"https:\/\/www.cdc.gov\/vaccinesafety\/pdf\/cdcstudiesonvaccinesandautism.pdf\">the CDC notes<\/a> that the agency either funded or conducted <a href=\"https:\/\/www.cdc.gov\/vaccinesafety\/concerns\/thimerosal\/timeline.html\">nine studies<\/a> between 1999 and 2010 that showed \u201cno link\u201d between childhood vaccinations and autism. Despite the public availability of these research results, the public\u2019s focus remains on the single \u201cpositive finding\u201d between research and autism published in 1998, even though this study has been thoroughly discredited.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>What is publication bias in research?
