<div class="articleBody"><nyt_text><p>Humans make errors. We make errors of fact and errors of judgment. We have blind spots in our field of vision and gaps in our stream of attention. Sometimes we can&#x2019;t even answer the simplest questions. Where was I last week at this time? How long have I had this pain in my knee? How much money do I typically spend in a day? These weaknesses put us at a disadvantage. We make decisions with partial information. We are forced to steer by guesswork. We go with our gut. </p> </nyt_text></div> <div class="articleInline runaroundLeft"> <!--h--> <div class="inlineImage module"> <div class="image"> <div class="icon enlargeThis"><a href="javascript:pop_me_up2('http://www.nytimes.com/imagepages/2010/05/02/magazine/02self-measurement-t_inline1.html','02self_measurement_t_inline1_html','width=485,height=580,scrollbars=yes,toolbars=no,resizable=yes')">Enlarge This Image</a></div> <a href="javascript:pop_me_up2('http://www.nytimes.com/imagepages/2010/05/02/magazine/02self-measurement-t_inline1.html','02self_measurement_t_inline1_html','width=485,height=580,scrollbars=yes,toolbars=no,resizable=yes')"> <img src="http://graphics8.nytimes.com/images/2010/05/02/magazine/02self-measurement-t_inline1/02self-measurement-t_inline1-articleInline.jpg" alt="" height="197" width="190"> </a> </div> <h6 class="credit">Horacio Salinas for The New York Times</h6> <p> </p> </div> </div> <div id="readerscomment" class="inlineLeft"> <h3>Readers' Comments</h3> <div class="content"> <blockquote>Share your thoughts.</blockquote> <ul class="more"> <li><a href="http://community.nytimes.com/comments/www.nytimes.com/2010/05/02/magazine/02self-measurement-t.html#postComment" rel="2p">Post a Comment &#xbb;</a></li> <li><a href="http://community.nytimes.com/comments/www.nytimes.com/2010/05/02/magazine/02self-measurement-t.html" rel="3v">Read All Comments (80) &#xbb;</a></li> </ul> </div></div> <div class="articleBody"> <p> That is, some of us do.
