In case you missed it, here is our most popular content from 2025

2025 is almost over, and it’s been a big year for Clearer Thinking. Alongside our core work of creating research-based content to help you think more clearly, make better decisions, broaden your understanding of the world, and ultimately improve your life, we also: 

• launched a bunch of new projects,

• started publishing long-form videos on YouTube, and

• ran more regular online events.

To help you catch up on anything you may have missed, we’ve curated our most popular work from the year, along with a few sister projects that might be valuable for you. We’ll also share where Clearer Thinking is headed in 2026, in case you’re interested.

Speaking of impact, we're actively looking for major funding.

1. Our most popular interactive tools 🛠️

In 2025, over 330,000 people from 117 countries worldwide completed at least one of our interactive tools to hone their thinking, change their habits, and make better decisions. Here are the three most often completed tools to date:

• The Ultimate Personality Test: Get a personalized report with your Big Five, Enneagram, and Jungian Type (inspired by MBTI)—the three most popular personality frameworks—all in one test. Note: This year, we've added a feature that allows you to generate a professionally designed PDF of your personality report. 

• How Rational Are You, Really?: Learn which of 16 reasoning styles you use, your overall level of rationality, and what you can do now to improve your rationality skills.

• Learn Your Philosophical Beliefs: Take this quiz to learn what philosophical beliefs you hold and discover whether these beliefs are predicted by your psychological traits.

In case you missed them, you may find it valuable to check out the new tools we launched this year:

• Craft Perfect Compliments: Learn a formula for crafting a successful compliment and feel more confident when sharing positive comments with others.

• The Imposter Syndrome Test: Learn about imposter syndrome, take the assessment to find out more about your own experiences, and discover strategies to combat imposter feelings.

• Understand Your Morality: Discover your unique moral compass through an interactive tool that analyzes your ethical decision-making across 15 different frameworks

• How Other People Can Make You Irrational: Uncover hidden influences that can cloud your judgment and lead to irrational beliefs and decisions, and gain insights into your own behavior and thought processes.

2. The Clearer Thinking Cognitive Assessment (with special discount for readers of this email) 🧠

This year, we’ve also launched the Clearer Thinking Cognitive Assessment, a scientifically designed test (grounded in years of research) that measures seven distinct dimensions of cognitive ability and provides an analysis of your strengths and areas for growth, along with tailored insights and recommendations for your career, learning, and more.

If you haven’t explored it yet and think a clearer picture of your cognitive skills would be valuable, we’re offering readers of this email a 50% discount. You’ll pay $17.50 instead of the regular $35. 

While almost all of the tools we create are free, this one is priced to support our mission and fund research and development.

3. Our most popular podcasts 🎙️

In 2025, we published 52 podcast episodes, totaling approximately 3,120 minutes of in-depth conversations on human psychology, philosophy, technology, and more. In total, the Clearer Thinking Podcast was downloaded over 315,000 times. 

Here are the three most popular podcast episodes we’ve published this year:

• The heavy price you'll have to pay to have a healthy relationship (with David Burns)

• A conversation about Borderline Personality Disorder (with Kayla Spicer)

• How f***ed is psychology? (with Adam Mastroianni)

4. Our most popular YouTube videos ▶️

For over a year now, Spencer Greenberg (Clearer Thinking’s founder) has been consistently publishing new videos on his YouTube channel as a complementary format to our written tools and articles.

These videos have received 390,000 total views, and we recently hit the milestone of 10,000 subscribers (if you are one of them, thank you!). Here are three of the most-watched videos so far:

• This Thought Experiment Reveals Your Hidden Moral Beliefs

• We studied 3691 people to bust IQ myths

• Why are so many people suddenly bisexual? Exploring 3 bi-potheses

Producing high-quality long-form video is time-intensive. If these videos are valuable to you (or you think they could be to someone else), subscribing to the channel is a simple way to support this work and help us reach more people we are less likely to reach on other platforms. Click here to subscribe now (it takes just a few seconds!). 

5. Our most popular articles 📝

In 2025, we published over 46 articles across a wide range of topics. In addition to our articles from previous years, we had more than 4 million views! Here are the three most popular articles published this year:

• How To Create Meaningful Connections By Asking Great Questions (by Sara Ness)

• Believing you only have one option is dangerous (by Travis M. and Spencer Greenberg)

• Three fresh takes on wisdom to help you become wiser (by Travis M., Sarah W. Woodhouse, and Spencer Greenberg)

Having over 430,000 newsletter subscribers certainly helps explain why our articles got so many views. So, you're reading this, thank you! We’re genuinely grateful for the time and attention you choose to give to our work.

6. New projects were born this year ✨

This year, we also saw some big sister-projects (from our parent organization, Spark Wave) come to life:

• PersonalityMap: Allows you to explore (completely free of charge) over 1 million human correlations spanning personality, demographics, behaviors, psychology, and beliefs.

• Hypothesize: An effortless (and also free) tool that allows you to analyze and visualize data, and conduct statistical tests in minutes using just your browser. And statistics, data science, and mathematical prior experience are not required, as all of its results come with built-in explanations.

7. More frequent online events 💬

Although we’ve been hosting online events since 2023, this year we really stepped it up and ran several exciting events with our audience. We’re truly grateful to everyone who joined (especially knowing how hard it can be to fit live events into a busy schedule).

Below are the recordings of some of our events this year:

• How To Disagree, Better

• The Art (And Science) of Healthy Relationships

• Mastering The Art Of Engaging Conversations

While these events are free to attend, the recordings are usually shared only with supporters. Consider this sample a small Christmas gift! 🎄

8. Our vision for 2026 (and how you can help)

In the year ahead, we plan to continue on our core work: conducting original research and creating more content and interactive tools grounded in those findings (plus, of course, in existing high-quality research).

To help address the replication crisis, we’ll also continue running replications of newly published psychology studies from top journals. You can learn more about our Transparent Replications project (and how to support it, such as by becoming a "replication scholar") by clicking here.

We’d also love to take on more ambitious projects that help build a strong foundation for reliable psychological research (free from harmful incentives). If this mission resonates with you, please consider supporting us, either through direct funding or by connecting us with someone who might be interested. Simply reply to this email, and we’d be happy to explore the possibilities.

And if funding isn’t the right fit, your ongoing support still matters a great deal. Reading our work, sharing it when you think it could be valuable to someone you know, and sending us feedback all make a real difference. These actions may seem small, but they really add up over time.

Do you have any feedback, including what you’d like to see more of from us in 2026? Feel free to respond to this email with your thoughts! 

Thank you again, and we hope to see you around in 2026.
