Code can make an analysis run; it cannot, by itself, show that the analysis answered the right question. As coding agents make implementation easier, the lasting value of data science remains the insight a team can defend: a clear question, evidence understood in context, a method suited to the task, and an interpretation that does not claim more than the data supports.
What “insight” means in data science
Insight is not simply a surprising chart, a statistically significant result, or a working program. It is a defensible connection between a question and evidence: what was observed, how the observations were produced, what the analysis can establish, and what remains uncertain.

Andrew Hinton makes this point in his September 30, 2026 article, “Insight Is Still the Currency of Data Science.” He writes: “I want to understand the question, what we found, and whether the evidence supports the conclusion.” That is a useful test for any analysis, whether a person or an agent wrote the code.

Code translates an analytical idea into an executable procedure, and reliable execution is necessary for many results. But a clean diff, a passing test, or a successful notebook run is evidence about implementation—not proof that the chosen data, method, or conclusion is scientifically sound.

Why coding agents make judgment more important, not less
Coding agents can reduce the effort involved in turning an instruction into code. That may leave more room to explore questions and alternatives, but it does not establish that teams will produce more discoveries or better analyses. Hinton’s case is a practitioner’s argument about where attention should go, not a measured productivity study. No numerical productivity gain or improvement in insight quality is established by the article.
The analyst still needs enough programming knowledge to inspect generated code, recognize an implementation that does not match the intended question, and understand the consequences of changes. Statistical and methodological judgment remain necessary too: a technically valid calculation can still rely on unsuitable assumptions or answer a different question from the one stakeholders care about.
Understanding the data is equally substantive. Analysts need to know how observations were collected or generated, what missing values and anomalies represent, and whether a measure means what its label suggests. Domain collaborators can provide essential context; that knowledge need not reside entirely in one data scientist.

A useful review does not ask the reviewer to infer the reasoning from a code diff alone. It gives them enough context to challenge the chain from question to conclusion. A notebook can do this, but so can an experiment interface or executable report if it exposes equivalent evidence.
- Question and scope: State the hypothesis or decision the analysis addresses, and identify the population, time period, or cases it concerns.
- Data and definitions: Identify the data source and version, relevant transformations, and definitions of important groups and measures. Explain meaningful missingness, exclusions, or anomalies.
- Method and assumptions: Describe the analytical approach, the assumptions that matter to the result, and why the method fits the question.
- Results and interpretation: Present the figures or outputs alongside uncertainty and limitations. Explain what the evidence supports and what it does not establish.
- Execution context: Where rerunning matters, record the environment and the steps needed to reproduce the computation. A successful rerun supports computational reproducibility; it does not independently validate the scientific conclusion.
The right review format depends on the work. Compare formats by whether a reviewer can inspect the data and assumptions, see outputs and relevant execution context, rerun or challenge the analysis, and obtain appropriate access to the underlying data. A recorded workflow helps only if reviewers can actually inspect the evidence they need.
Exploration and acceptance need different records
During exploration
Exploration is allowed to be provisional. The team may change its approach, investigate an unexpected pattern, or discover that the original question was poorly framed. The useful record is one that helps people follow and question the evolving work, rather than presenting every exploratory choice as settled.
Rank #4
When a change is offered for acceptance
A proposed change should have a coherent account of what prompted it, which alternatives were tried, and what evidence supports the conclusion. The reviewer should be able to distinguish the intended behavior from incidental implementation details and see the analytical reasoning behind the result.

Hinton captures the distinction this way: “An implementation produced quickly has value when it helps us discover something, and the work is incomplete until we can explain what we learned and why we believe it.”

A unit test can check a specified behavior without answering whether an agent accomplishes the intended task in realistic use. To evaluate an agent, define representative tasks and success criteria first. Anthropic’s January 9, 2026 engineering guide calls each attempt a trial and recommends multiple trials when outputs vary. It also advises choosing graders that fit the outcome and behavior being assessed.
- Define the task: Use tasks that resemble the work the agent is meant to perform, including relevant data, instructions, tools, and environmental constraints.
- Specify success before running trials: Decide what counts as success, what failures matter, and whether the evaluation is testing capability on new tasks or checking for regressions in known behavior.
- Run repeated trials when behavior is variable: A single successful attempt says little about reliability. Anthropic describes 20–50 simple tasks drawn from real failures as a reasonable starting point for an early evaluation—not a universal guarantee of sample size or quality.
- Choose a suitable grader: Code-based graders can check objective conditions; model-based graders can assess outputs that need judgment; human review can address context-sensitive outcomes. Each has limitations, so calibrate the grader against the behavior that matters.
- Inspect outcomes and traces: Review relevant transcripts or traces alongside the result, particularly when failures or unexpected behavior need explanation. Preserve the conditions under which each trial ran.
Report what the evaluation actually measures: one successful attempt, repeated reliability, or another goal defined for the task. Operational measures such as latency or cost belong in the evaluation when they affect the intended use. Anthropic’s guide reports that language-model performance on SWE-bench Verified rose from 40% to more than 80% in one year; that figure concerns that benchmark and period, not general coding-agent quality, data-science insight, or productivity.
Anthropic summarizes the purpose of evaluation this way: “Good evaluations help teams ship AI agents more confidently.” Evaluation can provide evidence about agent behavior, but it does not replace judgment about whether an analysis is meaningful or its conclusion justified.
What data scientists still need to know
Agents change the amount of implementation work a person may need to do directly; they do not eliminate the skills needed to direct and assess that work. A data scientist should be able to reason about the question, the data-generating process, the method, and the limits of the result. Programming fundamentals help make generated work inspectable and correctable, while collaboration with domain experts helps explain what the measurements represent.
For readers looking to deepen the analytical side, Data Science for Business: What You Need to Know About Data Mining and Data-Analytic Thinking by Foster Provost and Tom Fawcett is a relevant foundation. NYU Stern’s 2013 page described it as a textbook then used by more than a dozen universities in eight countries; that is historical adoption information, not a current count. The book’s focus, as described by NYU Stern and its publisher, is data-analytic thinking and extracting knowledge from data to address business problems.
