The comments illustrate my use of sports as an example of the point that everyone can think critically if the context is right. (Which shifts discussion from people's deficits as critical thinkers to examining how to create contexts that foster people getting access to their critical thinking intelligence.)

Caveat: written by Jonah Lehrer, whose star has fallen since it was shown that he recycled his own previous writing without noting it and he quoted people who other people, not him, had interviewed. Messages: K. Sawyer -- "Decades of research have consistently shown that brainstorming groups [who were told not to criticize anything proposed] think of far fewer ideas than the same number of people who work alone and later pool their ideas." Research by Nemeth -- Groups told that "most studies suggest that you should debate and even criticize each other's ideas" produced more ideas together and then subsequently on their own. Research by Uzzi -- (Lehrer's words) "The best Broadway shows were produced by networks with an intermediate level of social intimacy." Lehrer's take-home message -- "The fatal misconception behind brainstorming is that there is a particular script we should all follow in group interactions. The lesson of Building 20 is that when the composition of the group is right-enough people with different perspectives running into one another in unpredictable ways-the group dynamic will take care of itself. All these errant discussions add up."

"Nobody said it better than Francis Bacon, back in 1605: For myself, I found that I was fitted for nothing so well as for the study of Truth; as having a mind nimble and versatile enough to catch the resemblances of things … and at the same time steady enough to fix and distinguish their subtler differences; as being gifted by nature with desire to seek, patience to doubt, fondness to meditate, slowness to assert, readiness to consider, carefulness to dispose and set in order; and as being a man that neither affects what is new nor admires what is old, and that hates every kind of imposture."

"Ironically, U.S. military doctrine purports to value "critical" and "creative" thinking.  Unfortunately, that emphasis hardly fits with the realities of promotion and command selection.  A recent empirical analysis by faculty from West Point's Department of Behavioral Sciences and Leadership concluded that "promotion and command boards may actually penalize officers for their conceptual ability."  In other words, more intelligent, educated, and skeptical officers - those with "higher cognitive ability," according to the study -- don't fare so well in the competitive promotion game."

"The PowerPoint presentation BMJ 2007; 335 doi: http://dx.doi.org/10.1136/bmj.38994.480845.DE (Published 20 December 2007) Cite this as: BMJ 2007;335:1292 Article Related content Read responses (3) Article metrics David Isaacs, senior staff specialist1, Stephen Isaacs, consultant2, Dominic Fitzgerald, senior staff specialist3 Author Affiliations davidi@chw.edu.au The main purpose of a PowerPoint presentation is entertainment. Intellectual content is an unwarranted distraction. In preparing a PowerPoint presentation, aesthetics should transcend substance. The background colour scheme and logo for your slides should be selected for maximum emetogenic potential. The first inverse ridicule rule of PowerPoint presentation states: "The more lines of writing that can be coerced onto a slide and the smaller the font, the lower the risk of anyone criticising any data which has accidentally been included." The second rule states: "The number of slides you can show in your allotted time is inversely proportional to the number of awkward questions which can be asked at the end." PowerPoint has superseded the carousel era, when presentations were severely limited by the number of slots in the slide carousel and the risk of dropping the lot seconds before your talk. Plagiarism laws do not apply to PowerPoint, so cartoons of marginal relevance but high entertainment value can be downloaded and shown at suitable intervals to maintain audience mirth while minimising critical capacity. Research has shown that the ideal cartoon:data ratio is 5:1. The seasoned PowerPoint artist or PowerPointilliste has refined the presentation into a son-et-lumiere extravaganza, in which scattered dots and luminescent clumps of meaningless datasets hurtle on to the screen from all points of the compass, to the strident strains of Handel's Fireworks Music, building inexorably to a Fantasia-style Sorcerer's Apprentice climax. This fulfils an important s

"This is a mapping chart which describes, briefly, each cluster and each of the critical factors for learning and design. These factors map out the dynamic relationships between emergence and prescription within emergent learning, installations, events, and even emergent curricula .."

If form tends to follow function in design, what would the equivalent be in critical thinking? Are there forms of argumentation (assumptions, evidence, reasoning) that constrain the function (in contrast to the desired function dictating the form)? This line of inquiry led me to this reference.

Put the article together with the readers' comments and you have a year's worth of critical thinking exercises (assessing evidence, reasoning, and assumptions).

"In their writings, Buchanan and other libertarian thinkers lay out a vision for a certain kind of society. It's a society where capitalism has free rein and the rights of the wealthy few are protected, while the many are prevented from exercising countervailing power. It's a society where government is so shrunken as to be unrecognizable. In the country they envision, most protections that benefit average Americans have vanished: Social Security has been abolished, worker and public-health protections are gone, and public schools are shuttered in favor of private education. It's a country where national parks and water supplies are sold to the highest bidder. That's not a country most Americans would recognize. And it's not a country most of us, from any political party, would want to inhabit. "

"Learn to write for your most engaged reader, not your harshest critic. Reconnect with your work. Move ahead."

re: the psychologist Jonathan Haidt: In Haidt's view, the philosophers' dream of reason isn't just naïve, it is radically unfounded, the product of what he calls "the rationalist delusion." As he puts it, "Anyone who values truth should stop worshiping reason. We all need to take a cold, hard look at the evidence and see reasoning for what it is." Haidt sees two points about reasoning to be particularly important: the first concerns the efficacy (or lack thereof) of reasoning; the second concerns the point of doing so publicly: of exchanging reasons.

"Positive lead- ership rejects traditional deficit-based models of change management with their relentless drive to fix problems. Tombaugh (2005) advised managers that the challenge of maintaining a committed and motivated workforce is too difficult when the daily focus is on what is not working...."
