Release Date: August 14, 2025
Host: Mike Carruthers | OmniCast Media

Introduction

In this enlightening episode of Something You Should Know, host Mike Carruthers delves into two pivotal subjects shaping our modern lives: the intricate world of algorithms and the underrated significance of doing nothing. Through insightful conversations with experts Noah John Saracusa and Joseph Jabelli, the episode unpacks how algorithms influence our behaviors and the profound benefits that rest can have on our cognitive functions.

Section 1: Understanding Algorithms and Their Impact

Defining Algorithms Beyond Technology

Noah John Saracusa, an associate professor of mathematics and author of Robin Hood: Take Control of the Algorithms That Run Your Life, alongside Joseph Jabelli, provides a comprehensive breakdown of what algorithms truly are. They emphasize that algorithms aren't just complex computer codes but are processes for combining numbers to create useful outcomes.

[06:25] Joseph Jabelli: "An algorithm is just a process for kind of combining numbers in a certain way that ends up being useful for people."

The Ubiquity and Power of Algorithms

Algorithms underpin various aspects of our daily activities, from social media feeds to financial services. Jabelli illustrates this by comparing everyday decision-making to algorithmic processes.

[07:30] Joseph Jabelli: "When you get in your car and you want to drive to your local grocery store... Your head is actually playing all these algorithms all the time."

Data Collection and Privacy Concerns

A significant concern discussed is the vast amount of data companies collect to feed these algorithms, raising questions about privacy and surveillance. Jabelli points out the sheer scale of data availability today, which enables algorithms to influence behaviors in unprecedented ways.

[09:32] Joseph Jabelli: "They tend to be more than evil or good or bad or anything. They tend to be powerful."

Case Study: TikTok’s Recommendation Algorithm

The episode delves into TikTok's algorithm, illustrating how it scores and ranks videos based on user engagement metrics like likes, comments, and watch time. This scoring mechanism determines the content that surfaces on users' feeds.

[14:54] Joseph Jabelli: "TikTok uses some really fancy AI... it just multiplies those things, adds them up together, and it gives you a score."

Implications on User Behavior

Understanding the mechanics of these algorithms empowers users to navigate platforms more consciously. For instance, being aware that commenting on a conspiracy video might inadvertently promote its visibility can deter such engagements.

[22:06] Joseph Jabelli: "Knowing that... a comment of any kind... is going to count as engagement. It's going to give that video more score."

Section 2: The Neuroscience of Rest and Productivity

Challenging the Work-No Rest Paradigm

Joseph Jabelli, a neuroscientist and author of The Brain: How the Art and Science of Doing Nothing Can Improve Your Life, shifts the conversation to the importance of rest. He argues that constant busyness is counterproductive, emphasizing that rest activates the brain's default network, enhancing cognitive abilities.

[31:12] Joseph Jabelli: "When we rest, we now know that our brain activates a network... that has been shown to improve your intelligence, creativity, memory, problem-solving abilities."

The Default Network vs. Executive Network

Jabelli explains the distinction between the brain's executive network, responsible for focused tasks, and the default network, which is engaged during rest and fosters creativity and problem-solving.

[33:15] Joseph Jabelli: "Rest is the driving force behind all the things that you want to achieve in your work."

Practical Strategies for Incorporating Rest

The discussion offers actionable advice on integrating rest into daily routines, such as taking short breaks, engaging in physical exercise, and spending time in nature. These practices not only rejuvenate the mind but also bolster long-term productivity.

[35:54] Joseph Jabelli: "The more time you can spend doing nothing resting, the better it is for your brain."

Psychological Impacts of Overworking

Jabelli outlines the stages of overwork—from dissatisfaction to cynicism and eventually to anxiety and depression—highlighting the long-term psychological toll of neglecting rest.

[46:02] Joseph Jabelli: "There are these really interesting longitudinal studies... it takes up to three years to recover."

Balancing Work and Rest for Enhanced Performance

Emphasizing that rest leads to better performance, Jabelli shares studies indicating that periods of rest can significantly improve task execution, creativity, and overall mental health.

[39:59] Joseph Jabelli: "You will get more done, you will feel better, you'll notice that your memory is better, you'll notice that your creativity is better..."

Conclusion

This episode of Something You Should Know masterfully intertwines the complexities of algorithmic influence with the essential human need for rest. By demystifying algorithms, the discussion empowers listeners to engage with technology more mindfully. Simultaneously, the exploration into the neuroscience of rest offers a compelling case for re-evaluating our productivity habits. Together, these insights provide a balanced perspective on navigating the digital age while maintaining mental well-being.
