Baader–Meinhof Gang, see <a href="/wiki/Red_Army_Faction" title="Red Army Faction">Red Army Faction</a>.</div> <p>The <b>frequency illusion</b> (also known as the <b>Baader–Meinhof phenomenon</b>) is a cognitive bias in which a person notices a specific concept, word, or product more frequently after recently becoming aware of it. </p><p>The name "Baader–Meinhof phenomenon" was coined in 1994 by Terry Mullen in a letter to the <i><a href="/wiki/St._Paul_Pioneer_Press" title="St. Paul Pioneer Press">St. Paul Pioneer Press</a></i>.<sup id="cite_ref-1" class="reference"><a href="#cite_note-1"><span class="cite-bracket">&#91;</span>1<span class="cite-bracket">&#93;</span></a></sup> The letter describes how, after mentioning the name of the German terrorist group <a href="/wiki/Red_Army_Faction" title="Red Army Faction">Baader–Meinhof</a> once, he kept noticing it. This led to other readers sharing their own experiences of the phenomenon, leading it to gain recognition. It was not until 2005, when Stanford linguistics professor <a href="/wiki/Arnold_Zwicky" title="Arnold Zwicky">Arnold Zwicky</a> wrote about this effect on his blog, that the name "frequency illusion" was coined.<sup id="cite_ref-:12_2-0" class="reference"><a href="#cite_note-:12-2"><span class="cite-bracket">&#91;</span>2<span class="cite-bracket">&#93;</span></a></sup> </p> <meta property="mw:PageProp/toc" /> <div class="mw-heading mw-heading2"><h2 id="Causes">Causes</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Frequency_illusion&amp;action=edit&amp;section=1" title="Edit section: Causes"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>Several possible causes behind frequency illusion have been put forth.
