Marketecture Podcast Summary Episode 129: Justin Evans on “The Little Book of Data” Release Date: July 3, 2025
Host: Ari Paparo

Introduction

In Episode 129 of the Marketecture Podcast, host Ari Paparo welcomes Justin Evans, the author of “The Little Book of Data”, to discuss his new book and delve into the intricacies of data in today's business landscape. Despite the absence of co-host Eric Franchi due to the July 4th holiday, Ari ensures a rich and engaging conversation focused solely on data, its applications, and its universal principles.

Justin Evans: Background and Motivation

[03:10 - 04:29]
Justin Evans shares his professional journey, highlighting his roles at Nielsen, Comcast's Spotlight, and his current position as Head of Innovation and Insights at Samsung Ads. His motivation to write “The Little Book of Data” stemmed from observing the seismic shift towards data-centric business models, particularly at Comcast. He noticed a divide among professionals: those who embraced data and those who struggled to integrate it into their workflows. This division not only affected workplace dynamics but also mirrored in his personal life, where he saw varying comfort levels with data and AI across different professions.

Notable Quote:
"I saw that echoed a little bit in my personal life around New York City, where, you know, not all my friends are ed tech people, they're therapists, they're screenwriters, they are nonprofit leaders and so on. And I saw the same sort of split where some people were comfortable with data and AI and some people were not." — Justin Evans [04:15]

Core Principles of Data: The Four Data Superpowers

[06:15 - 07:31]
Justin introduces the Four Data Superpowers outlined in his book, which he likens to foundational gifts such as fire or electricity:

1. Omniscience:
   Data grants us the ability to gain comprehensive insights across various domains. For instance, in ad tech, retailers analyze sales data linked to loyalty cards, while in climate science, vast weather station data addresses global issues like climate change.

   Notable Quote:
   "Data gives us the power of omniscience. It allows us to in effect, see and know things from far flung parts of our existence." — Justin Evans [06:25]

2. Counting:
   The fundamental ability to quantify and measure phenomena, a principle Justin explores through his experiences at Nielsen.

3. Matching:
   Aligning disparate data points to uncover meaningful connections, exemplified by a biotech executive’s work in linking genomics to cancer treatments.

4. Scoring:
   Evaluating and prioritizing data to make informed decisions, which plays a crucial role in various industries beyond ad tech.

Example Discussion:
Justin recounts a poignant story about a biotech executive whose sister succumbed to cancer. Her work in genomics demonstrated how genetic mutations could predict effective treatments, drawing a parallel to how data is appended to customer databases in ad tech.

Data Across Different Domains

[14:42 - 16:42]
Justin discusses the universality of data principles across diverse fields such as biology, medicine, and public health. He highlights Travis May’s transition from Liveramp to founding Datavant, which leverages data in healthcare to bypass traditional clinical trials by utilizing historical data for testing treatments.

Notable Quote:
"The language between the woman who is the head epidemiologist at the Bureau of Communicable Diseases and someone from ad tech made sense and we could speak to each other." — Justin Evans [15:10]

This adaptability reinforces his belief that data concepts are "completely universal", and emphasizes the rapid applicability of data-driven approaches across sectors.

Psychological and Skill-Based Aspects of Data Integration

[10:50 - 12:45]
Justin addresses the common misconception that only quantitatively-minded individuals can excel with data. Instead, he advocates for:

• Confidence in Data Handling:
  Believing in one's ability to manipulate and understand data without requiring advanced degrees in computer science or statistics.

• Business-Centric Communication:
  Ensuring that data discussions are grounded in business terminology rather than technical jargon, fostering better collaboration between data experts and business leaders.

• Respect for Domain Knowledge:
  Valuing the business acumen and expertise of professionals, even if they aren't well-versed in data, to drive meaningful use cases.

Notable Quote:
"You don't need a computer science degree or a math degree or a stats degree to be able to understand data. You just need to understand these core ideas about how to manipulate it." — Justin Evans [11:00]

Personal Experiences and Anecdotes

[12:35 - 14:10]
Justin shares an anecdote from his tenure at Nielsen during a private equity takeover. He describes how data experts had to simplify complex data explanations to placate bankers unfamiliar with the intricacies of data systems. This experience underscored the importance of making data accessible and understandable to non-experts.

Notable Quote:
"Everything can be picked apart and everything can be understood by even the non expert." — Justin Evans [13:50]

Writing Process and Previous Works

[17:48 - 19:43]
Ari Paparo explores Justin’s journey as an author beyond “The Little Book of Data”. Justin reveals his aspiration to become a novelist, initially aiming to write spy thrillers. After facing rejections, he pivoted to gothic suspense novels inspired by his Southern heritage, resulting in books centered around themes like demon possession and ghosts.

Notable Quote:
"I was an English major undergrad, and I actually think that's been a kind of a weird driver of my own career success." — Justin Evans [12:45]

Justin humorously accepts Ari’s challenge to write a “data thriller,” expressing enthusiasm for expanding his literary repertoire.

Audiobook Recording Experience

[19:19 - 20:25]
The conversation shifts to the process of recording audiobooks. Justin details his experience recording the “Little Book of Data” audiobook over two days, juxtaposing it with Ari's more extended recording process for his own book. Despite the grueling nature, Justin finds enjoyment in the experience, especially being in the same studio where his favorite Harry Potter audiobook was recorded.

Notable Quote:
"I did lose my mind. Yes, you would have." — Justin Evans [20:13]

Key Takeaways for Ad Tech Professionals

[16:48 - 17:28]
Justin emphasizes that ad tech professionals have the unique opportunity to “step back from the real nitty gritty minutia” and innovate by focusing on solving marketers' business problems. With the advent of AI tools, he argues that data experts should prioritize business-oriented solutions over purely data-driven approaches.

Notable Quote:
"As a data person, I think that we should think less like data people and think more like business people and focus on business problems." — Justin Evans [16:48]

Conclusion

Ari Paparo wraps up the episode by highlighting Justin Evans’ “The Little Book of Data” as a must-read for anyone looking to understand the foundational principles of data beyond mere number crunching. Justin encourages listeners to purchase the book, available in both hardcover and audiobook formats, and expresses enthusiasm for future literary projects.
