It&#8217;s hard to do that online! But, as you&#8217;ll see, junk food is an analogy for the design principle we&#8217;re talking about today, so it&#8217;s totally relevant and justified. And engaging all five senses can help you retain information, so if you need an excuse for an unhealthy snack (or healthy, that&#8217;s fine!) it is fully recommended for your educational outcomes.<\/p>\n<div id=\"attachment_1941\" style=\"width: 650px\" class=\"wp-caption alignnone\"><a href=\"https:\/\/flic.kr\/p\/dQKU79\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-1941\" class=\"wp-image-1941 size-full\" src=\"https:\/\/murrowcourses.com\/graphics\/wp-content\/uploads\/2019\/05\/candy.jpg\" alt=\"\" width=\"640\" height=\"365\" srcset=\"https:\/\/murrowcourses.com\/graphics\/wp-content\/uploads\/2019\/05\/candy.jpg 640w, https:\/\/murrowcourses.com\/graphics\/wp-content\/uploads\/2019\/05\/candy-300x171.jpg 300w\" sizes=\"auto, (max-width: 640px) 100vw, 640px\" \/><\/a><p id=\"caption-attachment-1941\" class=\"wp-caption-text\">Photo by <a href=\"https:\/\/flic.kr\/p\/dQKU79\">Neff Conner\/Flickr<\/a><\/p><\/div>\n<p><span class=\"subhead\">Lecture: The problem with &#8220;chartjunk&#8221;<\/span><\/p>\n<p>We previously talked about design philosophy and Edward Tufte&#8217;s principles of data density and data-ink ratio.
