You're Not Broken for Scrolling at 2 AM — Your Brain Might Just Be Looking for Something Sleep Apps Can't Give

Those nights when your brain won't shut off and you're scrolling social media at 2 AM? If you've ever wondered whether your focus issues and sleep problems are connected, this research has answers. A new study of over 1,300 adults reveals that ADHD traits, whether you're diagnosed or just suspect you might have a few traits, are correlated with insomnia and lower quality of life. And here's what floored me: I always blamed my decades of insomnia on anxiety and rumination, but this research shows there's more to the story.

WTH does that mean? People with higher ADHD traits (even without a diagnosis) had significantly more severe insomnia, worse sleep quality, and tended to be night owls. But here's the surprising part: while these sleep problems didn't explain the link between ADHD and depression, insomnia turned out to be a big part of the puzzle behind lower life satisfaction. In other words, the sleep issues aren't causing the depression, but they ARE making life feel harder overall. Will sleep make your life rainbows and butterflies? Well, let’s not pretend that we aren’t all under a variety of stresses (life stress, money, and mental health quirks still matter!).

Key Insights:

1. You don't need an ADHD diagnosis for this to apply - the study measured traits on a spectrum using a self-report scale. For example, if you sometimes struggle with focus, organization, or feel restless, these sleep connections could affect you, too.

2. The insomnia-ADHD connection is stronger than many realize. Many of us battle revenge bedtime procrastination and late-night scrolling that triggers rumination - these might not be "bad habits" but your ADHDish (again, full ADHD diagnosis not required) brain seeking stimulation when it should be winding down. Folks in the high-ADHD-trait group logged about 2× the insomnia-severity scores of low-trait peers.

3. Targeting insomnia could be transformative. After essentially curing my own chronic insomnia, I can't emphasize enough how different life feels when you're not constantly exhausted. Tracking sleep patterns with a wearable can reveal patterns your tired brain misses.

Read the full study for the complete methodology showing how ADHD traits affect sleep across the spectrum, plus clinical implications for treatment.

Why Everyone's Talking About Instagram Content Indexing in Google Search

First, Google started including videos in its AI overviews, and now Instagram content is being indexed by search engines. Are we watching search and social media merge into one thing instead of two? It's starting to look that way. This shift means your Instagram posts could now reach people who've never even opened the app - turning every post into potential search engine content.

Key Insights:

1. Your Instagram content now has a much longer shelf life - posts from January 2020 onward can appear in search results, meaning that evergreen content you created years ago could still drive traffic today.

2. Location-based businesses get a huge advantage here - adding location tags and keywords like "Italian bistro in downtown Calgary" in your captions helps you show up in local searches without needing a website.

3. The basics matter more than ever - alt text, captions with natural keywords, and subtitles on videos aren't just accessibility features anymore. They're your ticket to search visibility beyond Instagram's walls.

Read the full article for five specific optimization strategies and the exact criteria Instagram uses to determine which accounts are eligible for indexing.

How to Batch Your Week Based on Chronotype and Task Type

Why are some people roaring at 5 am while others get their second (or first) wind at night? That's your body's natural rhythm trying to tell you something. This guide shows you how to stop fighting your internal clock and start designing a schedule that actually works with it. Chronotype is a scientifically backed concept (and even backed by evolution science), but without getting into all that, let’s get into what this means for us today.

Key Insights:

1. Most tasks fall into five categories—deep work, shallow work, creative work, collaborative work, and recovery time—and matching these to your energy peaks can transform your productivity.

2. Your weekly energy curve varies by chronotype. For example, Bears do best with planning on Monday mornings and deep work Tuesday through Thursday mid-morning, while Wolves should save their strategic thinking for late afternoon.

3. Supporting each task type with the right tools matters. Try binaural beats for deep work, lo-fi for creative sessions, and complete silence for recovery blocks to maximize your natural rhythms.

Read the full article for complete weekly schedules for all four chronotypes and specific sound recommendations for each task type.

These 7 Perplexity Features Make ChatGPT, Claude, and Gemini Look Trash

Remember when "enterprise-grade AI" meant remortgaging your house to afford it? Perplexity just crashed that exclusive party. I've gone from "it's nice to have" to switching my default search engine to Perplexity to full-on evangelistic about this tool (not sponsored -- but should be, hey there Perplexity!). Despite all of this, I didn't know at least half of these features!

Key Insights:

1. The "best" button automatically selects the optimal AI model for your specific query - research might use Sonar while coding switches to Claude, eliminating the guesswork of which tool to use when. (01:31)

2. Deep Research mode can crawl 90+ sources (including Reddit threads, academic papers, or SEC filings) to validate business ideas and find real problems people need solved - far beyond what other AI tools offer. (03:30)

3. Labs feature includes AI agents that can build complete business plans, brand mood boards, and even start coding MVP features from a single idea prompt. (05:56)

4. Automated tasks deliver personalized research on schedule. For example, setting up weekly AI trend reports that compile major launches, startup moves, and innovations every Monday morning. (10:21)

5. Unlike Claude's interface, Perplexity lets you use voice prompting with Claude 4.0 Sonnet - combining the best of both platforms in ways the original tools don't even offer. (11:52)

Can You Stop ChatBots from Confidently Hallucinating? [multiple links below]

Here's a fun fact that'll make you side-eye your AI assistant: When Carnegie Mellon researchers tested ChatGPT-4 and Gemini, these digital know-it-alls became MORE confident after completely bombing their tests. In one task, Gemini predicted it would identify about 10 sketches correctly but actually got less than 1 right, yet afterward estimated it had gotten 14 correct [CMU Study]. It's like that friend who insists they're crushing it at karaoke while the whole bar winces. But wait, it gets weirder. Google DeepMind found that if you so much as question an AI's answer (even when the AI is actually RIGHT), it often freaks out and abandons the correct response entirely [Google DeepMind Research]. For those of us using AI to draft client proposals or crunch numbers, this isn't just quirky. It's costing us serious time and credibility. I learned this the hard way when AI confidently told me a "fact" about a study I was writing up and I had zero memory of that fact from the study. It turns out, it was made up. Thank goodness for my obsessive fact-checking nature. The silver lining? MIT's new "Thermometer" method cuts calibration error [MIT Research].

Key Insights:

1. Your AI Has Main Character Energy (In the Worst Way): Unlike us mere mortals who get humbled by mistakes, ChatGPT-4 stayed cocky and Gemini got COCKIER in multiple tasks where they flopped, from NFL predictions to trivia questions. The CMU study tested this across five different tasks over 18 months [CMU Study]. That "definitive" answer about your industry's growth rate? Yeah, might want to fact-check that.
   

2. The Fragile Ego Problem: Push back on your AI, even incorrectly, and watch it crumble faster than a cookie in milk. Google DeepMind researchers found that LLMs exhibit "choice-supportive bias" and often ditch their correct answers when challenged [Google DeepMind Research]. It's like dealing with that one coworker who can't handle any feedback.
   

3. Hope for the Overconfident Bot: MIT researchers developed a method that significantly improves how well AI language models know when they might be wrong - reducing calibration errors by 50-70% in controlled tests. Early but promising results for AI safety [MIT Research]. Asking GPT-3.5 to list facts, cite sources, then reflect cut the error by ~24% in the Fact-and-Reflection Study. Smaller tasks & other models may differ - still a neat way to curb over-confidence.” My new favorite prompt hack: "Answer this, then tell me why you might be wrong."
