Causal Inference Is Different in Business

Summary

This article argues that applied causal inference often overemphasizes academic rigor, leading to wasted resources and delayed impact, particularly in fast-paced tech environments. It introduces a "final vs. constructive decisions" framework, where constructive decisions move a process forward with lower stakes (e.g., "Should we explore this feature?"), while final decisions commit significant resources or change direction with high stakes (e.g., "Should we invest $2M?"). The author proposes three rules for effective causal inference: start with the business problem, not the method; use simpler methods if they suffice; and apply the 80/20 rule to causal inference projects, focusing effort where it matters most for the overall decision. The piece highlights the importance of understanding the "problem behind the problem" and the opportunity cost of excessive rigor when simpler associative analyses or common sense could provide sufficient answers for constructive decisions.

Key takeaway

For Product Managers evaluating new features or strategic directions, align your causal inference rigor with the decision's gravity. For "constructive" decisions, simpler analyses often suffice to move forward, saving time and resources. For "final" decisions, where significant investment or irreversible changes are at stake, a more rigorous causal approach is warranted. Always ensure your analysis addresses the core business problem and contributes proportionally to the overall decision, rather than over-investing in a single, precise estimate.

Key insights

Match causal inference rigor to decision gravity to optimize resource allocation and impact.

Principles

• Prioritize the business problem over the analytical method.
• Simpler solutions are often sufficient for constructive decisions.
• Causal inference is one input, not the sole determinant.

Method

Frame decisions as "final" (high stakes) or "constructive" (process-forwarding) to guide the appropriate level of causal inference rigor, ensuring alignment with broader business questions.

In practice

• Before starting, ask "so-what?" about potential answers.
• Consider common sense or associative analysis first.
• Allocate effort across all decision dimensions, not just causal.
