For Proof, Look at Their Strategic Plans. <\/a><!--(Sept. 13, 2021)--> <small>(Articles from the <i>Chronicle of Higher Education<\/i>, such as this one, can be accessed by UF students and staff for free from a UF computer or via a VPN connection to the UF computer network.)<\/small> &#8220;Over the last two decades, the U.S. News `Best College&#8217; rankings have sustained intense criticism for <!--rewarding wealthier institutions, for weighting `inputs' over `outputs,' and for--> &#8230; being poor indicators of colleges\u2019 quality. Yet public colleges are still using the rankings and those they inspired to measure their own success. &#8230; <!--About a quarter of the [strategic] plans [of the country\u2019s 100-largest public 4-year universities] explicitly affirm the importance of rising in national rankings. ... --> This prevalence &#8230; is a striking testament to public higher education\u2019s continued pursuit of an accolade that many have said is antithetical to the mission of state-funded education. &#8230; <!--Graduation rates and retention account for 22 percent of U.S. News\u2019s calculation. But F.

Some plans acknowledge the troubling downstream effects of U.S. News\u2019s supremacy, and promise they won\u2019t blindly chase the prestige that rankings promise. `Setting goals that strategically align with improving national rankings to increase visibility and enhance institutional reputation can inadvertently negatively affect demographic diversity and limit student access,' Florida International University\u2019s strategic plan reads. ...--> <!--The pattern among some public colleges of privileging rankings in their plans is especially striking because previous analyses have found that the rankings exacerbate inequality.--> A 2017 analysis by Politico showed that the rankings created incentives for universities to favor wealthy students. &#8230; U.S. News says its rankings are designed to give students and their families clear, helpful information that they can use to decide where to go to college. That\u2019s not what it does, according to [F. King] Alexander, [former president of Louisiana State and Oregon State Universities]. `It\u2019s designed for the wealthy and wealthy schools, and that\u2019s always been what it\u2019s about,&#8217; he said. `It\u2019s been a quiet protection of the privileged class.'&#8221;<br><\/li>\n\n\n\n<li><a href=\"https:\/\/news.stanford.edu\/2009\/08\/24\/multitask-research-study-082409\/\">Media multitaskers pay mental price, Stanford study shows.<\/a> <i>Think you can talk on the phone, send an instant message and read your e-mail all at once?
