Think Again About Outsourcing Your Thinking 2.0 (if you can)

/ SupremeCmdr / 1 Comment

Michael Gerlich, head of the Centre for Strategic Corporate Foresight and Sustainability at SBS Swiss Business School, began studying the impact of generative AI on critical thinking because he noticed the quality of classroom discussions decline. Sometimes he’d set his students a group exercise, and rather than talk to one another they continued to sit in silence, consulting their laptops. He spoke to other lecturers, who had noticed something similar. Gerlich recently conducted a study, involving 666 people of various ages, and found those who used AI more frequently scored lower on critical thinking. (As he notes, to date his work only provides evidence for a correlation between the two: it’s possible that people with lower critical thinking abilities are more likely to trust AI, for example.) Like many researchers, Gerlich believes that, used in the right way, AI can make us cleverer and more creative – but the way most people use it produces bland, unimaginative, factually questionable work.

Yikes.

Clearing Up Myths About Older Workers

/ SupremeCmdr / Leave a comment

In 2001, only about 1 out of every 7 U.S. workers was 55 or older. By 2021, the number jumped to almost 1 out of every 4 workers (a 93% increase). That’s almost twice the proportion of older workers as before.3 Older workers are staying on the job longer for various reasons, ranging from financial needs to the joy of work.  More people are working past the age when they might have retired. They might be responding to the increase in the Social Security full retirement age, needing money or health insurance, or simply enjoying their jobs and being around their friends at work.⁴ Clearing Up Myths About Older Workers While Understanding and Supporting an Aging Workforce — https://blogs.cdc.gov/niosh-science-blog/2023/09/25/older-workers/

I’ve Been in Physical Therapy For Over Three Months

Less is more.

We’ve turned the idea of “exercise” into something so loaded these days, only to be validated by a specific kind of intensity. Just uttering the word exercise now can ignite an all-or-nothing mindset, filled with protein obsessions, endless wearable fitness trackers, or even a costly membership to an elite wellness club.

I used to be a runner. Quite a few years ago my knees told me not to run anymore.

I joined the Y and did the elliptical and treadmills until my knees complained some more. I moved my exercise routine to the resistance machines. Then Covid hit, I cancelled my membership and the months turned into years away from the gym.

I found some resistance bands in the house and started some simple exercises at home. I rejoined the Y and started back with the resistance machines.

Earlier this year my employer offered access to online virtual physical therapy. I took advantage of this benefit from https://www.hingehealth.com/ and have been in physical therapy now for over three months. Less pain (especially my cervical spine, the result of a near fatal encounter with a car), less stiffness, better flexibility, and gradually improving strength. The beauty of the program is availability on demand and it is 100% HEP (home exercise program). Sessions are 10-12 minutes long and you don’t have to leave the house.

Less is more.

Tsundoku (guess the disease)

“All those books you haven’t read are indeed a sign of your ignorance. But if you know how ignorant you are, you’re way ahead of the vast majority of other people.” Jessica Stillman

Tsundoku is the Japanese word for the stack(s) of books you’ve purchased but haven’t read. Its morphology combines tsunde-oku (letting things pile up) and dokusho (reading books). The Japanese call this practice tsundoku, and it may provide lasting benefits — https://bigthink.com/neuropsych/do-i-own-too-many-books/

Thinking Styles – What’s Your Style?

Read this thinking style pyramid and refer back to it as often as needed.

We are all suckers for click bait. I started with this:

Older Adults Face Higher Cancer Risk From Alcohol, Even at Low or Moderate Levels – https://www.medscape.com/viewarticle/older-adults-face-higher-cancer-risk-alcohol-even-low-or-2025a

Scary stuff if you’re an older adult! I should STOP DRINKING ALCOHOL.

But what if this study is wrong? See pyramid above. Sensing bias in the article I took a look at the comments. Dr. Bradley Fawkes’ comment was noteworthy. In the results section of the study you’ll find this:

“While no associations were found for low- or moderate-risk drinking patterns vs occasional drinking among individuals without socioeconomic or health-related risk factors…” Alcohol Consumption Patterns and Mortality Among Older Adults With Health-Related or Socioeconomic Risk Factors – https://jamanetwork.com/journals/jamanetworkopen/fullarticle/2822215

So in the absence of socioeconomic or health-related risk factors no associations were found.

Cheers!

When People Did Not Have Access to Mobile Internet, they Spent More Time Socializing in Person, Exercising, and Being in Nature.

Our results provide evidence that blocking mobile internet from smartphones for 2 weeks can produce significant improvements for SWB (subjective well being), mental health, and the objectively measured ability to sustain attention. Even those who did not fully comply with the intervention experienced significant, though more modest, improvements. These findings suggest that constant connection to the online world comes at a cost, since psychological functioning improves when this connection is reduced. Blocking mobile internet on smartphones improves sustained attention, mental health, and subjective well-being – PNAS Nexus, Volume 4, Issue 2, February 2025, pgaf017, https://doi.org/10.1093/pnasnexus/pgaf017

Excuse me please, I have to check my phone.
