This has consequences for the quality of decisions made by large numbers of people, such as in <a href="/wiki/General_election" title="General election">general elections</a>, where the probability of any one <a href="/wiki/Vote" class="mw-redirect" title="Vote">vote</a> changing the outcome is very small. </p><p>The term is most often found in <a href="/wiki/Economic" class="mw-redirect" title="Economic">economics</a>, particularly <a href="/wiki/Public_choice_theory" class="mw-redirect" title="Public choice theory">public choice theory</a>, but also used in other disciplines which study <a href="/wiki/Rationality" title="Rationality">rationality</a> and choice, including <a href="/wiki/Philosophy" title="Philosophy">philosophy</a> (<a href="/wiki/Epistemology" title="Epistemology">epistemology</a>) and <a href="/wiki/Game_theory" title="Game theory">game theory</a>. </p><p>The term was coined by <a href="/wiki/Anthony_Downs" title="Anthony Downs">Anthony Downs</a> in <i><a href="/wiki/An_Economic_Theory_of_Democracy" title="An Economic Theory of Democracy">An Economic Theory of Democracy</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> </p> <meta property="mw:PageProp/toc" /> <div class="mw-heading mw-heading2"><h2 id="Example">Example</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Rational_ignorance&amp;action=edit&amp;section=1" title="Edit section: Example"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>Consider an employer attempting to choose between two candidates offering to complete a task at the cost of $10/hour. The length of time needed to complete the task may be longer or shorter depending on the skill of the person performing the task, so it is in the employer's best interests to find the fastest worker possible. Assume that the cost of another day of interviewing the candidates is $100. If the employer had deduced from the interviews so far that both candidates would complete the task in somewhere between 195 and 205 hours, it would be in the employer's best interests to choose one or the other by some easily applied metric (for example, flipping a coin) rather than spend the $100 on determining the better candidate, saving at most $100 in labor. In many cases, the decision may be made on the basis of <a href="/wiki/Heuristics_in_judgment_and_decision_making" class="mw-redirect" title="Heuristics in judgment and decision making">heuristics</a>; a simple decision model which may not be completely accurate. For example, in deciding which brand of prepared food is most nutritious, a shopper might simply choose the one with (for example) the lowest amount of sugar, rather than conducting a research study of all the positive and negative factors in nutrition. </p> <div class="mw-heading mw-heading2"><h2 id="Applications">Applications</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Rational_ignorance&amp;action=edit&amp;section=2" title="Edit section: Applications"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <link rel="mw-deduplicated-inline-style" href="mw-data:TemplateStyles:r1251242444"><table class="box-Unreferenced_section plainlinks metadata ambox ambox-content ambox-Unreferenced" role="presentation"><tbody><tr><td class="mbox-image"><div class="mbox-image-div"><span typeof="mw:File"><a href="/wiki/File:Question_book-new.svg" class="mw-file-description"><img alt="" src="//upload.wikimedia.org/wikipedia/en/thumb/9/99/Question_book-new.svg/50px-Question_book-new.svg.png" decoding="async" width="50" height="39" class="mw-file-element" srcset="//upload.wikimedia.org/wikipedia/en/thumb/9/99/Question_book-new.svg/75px-Question_book-new.svg.png 1.5x, //upload.wikimedia.org/wikipedia/en/thumb/9/99/Question_book-new.svg/100px-Question_book-new.svg.png 2x" data-file-width="512" data-file-height="399" /></a></span></div></td><td class="mbox-text"><div class="mbox-text-span">This section <b>does not <a href="/wiki/Wikipedia:Citing_sources" title="Wikipedia:Citing sources">cite</a> any <a href="/wiki/Wikipedia:Verifiability" title="Wikipedia:Verifiability">sources</a></b>.<span class="hide-when-compact"> Please help <a href="/wiki/Special:EditPage/Rational_ignorance" title="Special:EditPage/Rational ignorance">improve this section</a> by <a href="/wiki/Help:Referencing_for_beginners" title="Help:Referencing for beginners">adding citations to reliable sources</a>.

If the difference in value between a quality product and a poor product is less than the cost to perform the research necessary to differentiate between them, then it is more rational for a consumer to just take his chances on whichever of the two is more convenient and available. Thus, it is in the interest of the producer of a lower value product to proliferate features, options, and package combinations which will tend to increase the number of shoppers who decide it's too much trouble to make an informed decision. </p> <div class="mw-heading mw-heading3"><h3 id="In_politics">In politics</h3><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Rational_ignorance&amp;action=edit&amp;section=4" title="Edit section: In politics"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>Politics and elections especially display the same dynamic. By increasing the number of issues that a person needs to consider to make a rational decision about candidates or policies, politicians and pundits encourage <a href="/wiki/Single-issue" class="mw-redirect" title="Single-issue">single-issue</a> voting, <a href="/wiki/Party-line_vote" title="Party-line vote">party-line</a> voting, <a href="/wiki/Jingoism" title="Jingoism">jingoism</a>, selling votes, or dart-throwing all of which may tip the playing field in favor of politicians who do not actually represent the electorate. </p><p>This does not mean that voters make poor and biased decisions: rather that in carrying out their everyday responsibilities (like working and taking care of a family), many people do not have the time to devote to researching every aspect of a candidate's policies. So many people find themselves making rational decisions meaning they let others who are more versed in the subject do the research and they form their opinion based on the evidence provided. They are being rationally ignorant not because they don't care but because they simply do not have the time. </p><p>Because the cost/benefit ratio increases with increasing costs <em>or</em> decreasing the benefit, the same effect can occur when politicians protect their policy decisions from the preferences of the public. To the degree that the electorate perceives their individual votes to count for less, they will have less incentive to spend any time actually learning any details about the candidate(s). </p><p>A more nuanced example occurs when a voter identifies with a particular political party, akin to the adoption of a favorite movie critic. Based on prior experience a responsible voter will seek politicians or a political party that draws conclusions about social policy that are similar to what their own conclusions would have been had they done a complete analysis. But when voters find themselves agreeing with the same party or politician across a number of election cycles, many voters simply trust that the same will continue to be true and "vote the ticket," also referred to as <a href="/wiki/Straight-ticket" class="mw-redirect" title="Straight-ticket">straight-ticket</a> voting, instead of wasting time on a complete investigation. </p> <div class="mw-heading mw-heading2"><h2 id="Criticisms">Criticisms</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Rational_ignorance&amp;action=edit&amp;section=5" title="Edit section: Criticisms"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>Much of the empirical support for the idea of rational ignorance was drawn from studies of <a href="/wiki/Voter_apathy" class="mw-redirect" title="Voter apathy">voter apathy</a>, which reached particularly strong conclusions in the 1950s.<sup id="cite_ref-2" class="reference"><a href="#cite_note-2"><span class="cite-bracket">&#91;</span>2<span class="cite-bracket">&#93;</span></a></sup> However, apathy appeared to decline sharply in the 1960s as concern about issues such as the <a href="/wiki/Vietnam_War" title="Vietnam War">Vietnam War</a> mounted, and political <a href="/wiki/Polarization_(politics)" class="mw-redirect" title="Polarization (politics)">polarization</a> increased.<sup id="cite_ref-3" class="reference"><a href="#cite_note-3"><span class="cite-bracket">&#91;</span>3<span class="cite-bracket">&#93;</span></a></sup> This is consistent with expectations from Public Choice Theory; as voters' interest in the results of policy decisions increase, the perceived benefit of the analysis (or the trip to the ballot box) increases, so more people will consider it rational to repair their ignorance. </p><p>There also may be situations when "the individual may perceive the situation as one that has carry over benefits to other situations, and treat the learning as a capital investment with payoff beyond the specific situation in which it is presented," and not a waste of time even though the time invested in the learning my not have immediate payoff.

The investment of time and energy on learning about the specified subject has ramifications on other decision areas. Individuals sometimes ignore this when unconsciously assessing the investment cost versus payout. The external benefits of acquiring knowledge in one area—those benefits occurring in other decision areas—are therefore subject to being overlooked. </p> <div class="mw-heading mw-heading2"><h2 id="See_also">See also</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Rational_ignorance&amp;action=edit&amp;section=6" title="Edit section: See also"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <style data-mw-deduplicate="TemplateStyles:r1239009302">.mw-parser-output .portalbox{padding:0;margin:0.5em 0;display:table;box-sizing:border-box;max-width:175px;list-style:none}.mw-parser-output .portalborder{border:1px solid var(--border-color-base,#a2a9b1);padding:0.1em;background:var(--background-color-neutral-subtle,#f8f9fa)}.mw-parser-output .portalbox-entry{display:table-row;font-size:85%;line-height:110%;height:1.9em;font-style:italic;font-weight:bold}.mw-parser-output .portalbox-image{display:table-cell;padding:0.2em;vertical-align:middle;text-align:center}.mw-parser-output .portalbox-link{display:table-cell;padding:0.2em 0.2em 0.2em 0.3em;vertical-align:middle}@media(min-width:720px){.mw-parser-output .portalleft{clear:left;float:left;margin:0.5em 1em 0.5em 0}.mw-parser-output .portalright{clear:right;float:right;margin:0.5em 0 0.5em 1em}}</style><ul role="navigation" aria-label="Portals" class="noprint portalbox portalborder portalright"> <li class="portalbox-entry"><span class="portalbox-image"><span class="noviewer" typeof="mw:File"><span><img alt="" src="//upload.wikimedia.org/wikipedia/commons/thumb/c/cd/Socrates.png/18px-Socrates.png" decoding="async" width="18" height="28" class="mw-file-element" srcset="//upload.wikimedia.org/wikipedia/commons/thumb/c/cd/Socrates.png/27px-Socrates.png 1.5x, //upload.wikimedia.org/wikipedia/commons/thumb/c/cd/Socrates.png/36px-Socrates.png 2x" data-file-width="326" data-file-height="500" /></span></span></span><span class="portalbox-link"><a href="/wiki/Portal:Philosophy" title="Portal:Philosophy">Philosophy portal</a></span></li></ul> <ul><li><a href="/wiki/Agency_(sociology)" title="Agency (sociology)">Agency (sociology)</a></li> <li><a href="/wiki/Argument_from_authority" title="Argument from authority">Argument from authority</a></li> <li><a href="/wiki/Bounded_rationality" title="Bounded rationality">Bounded rationality</a></li> <li><a href="/wiki/Mooers%27s_law" title="Mooers&#39;s law">Mooers's law</a></li> <li><a href="/wiki/Rational_irrationality" title="Rational irrationality">Rational irrationality</a></li> <li><a href="/wiki/Satisficing" title="Satisficing">Satisficing</a></li> <li><a href="/wiki/Sociology_of_scientific_ignorance" title="Sociology of scientific ignorance">Sociology of scientific ignorance</a></li></ul> <div class="mw-heading mw-heading2"><h2 id="References">References</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Rational_ignorance&amp;action=edit&amp;section=7" title="Edit section: References"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <style data-mw-deduplicate="TemplateStyles:r1239543626">.mw-parser-output .reflist{margin-bottom:0.5em;list-style-type:decimal}@media screen{.mw-parser-output .reflist{font-size:90%}}.mw-parser-output .reflist .references{font-size:100%;margin-bottom:0;list-style-type:inherit}.mw-parser-output .reflist-columns-2{column-width:30em}.mw-parser-output .reflist-columns-3{column-width:25em}.mw-parser-output .reflist-columns{margin-top:0.3em}.mw-parser-output .reflist-columns ol{margin-top:0}.mw-parser-output .reflist-columns li{page-break-inside:avoid;break-inside:avoid-column}.mw-parser-output .reflist-upper-alpha{list-style-type:upper-alpha}.mw-parser-output .reflist-upper-roman{list-style-type:upper-roman}.mw-parser-output .reflist-lower-alpha{list-style-type:lower-alpha}.mw-parser-output .reflist-lower-greek{list-style-type:lower-greek}.mw-parser-output .reflist-lower-roman{list-style-type:lower-roman}</style><div class="reflist"> <div class="mw-references-wrap"><ol class="references"> <li id="cite_note-1"><span class="mw-cite-backlink"><b><a href="#cite_ref-1">^</a></b></span> <span class="reference-text">Downs.
