Mercor CEO Brendan Foody on training AI with elite human experts, the rapid rate of model improvement, and the future of knowledge work.

Replace 'Vibe-Based' Interviews with Real Work Sample Projects

A common hiring mistake is prioritizing a conversational 'vibe check' over assessing actual skills. A much better approach is to give candidates a project that simulates the job's core responsibilities, providing a direct and clean signal of their capabilities.

AI Will Automate 75% of Expert Work; The Last 25% Becomes the New Value Frontier

AI models will quickly automate the majority of expert work, but they will struggle with the final, most complex 25%. For a long time, human expertise will be essential for this 'last mile,' making it the ultimate bottleneck and source of economic value.

AI Trainer Jobs Will Require Domain Expertise, Not Technical AI Skills

The emerging job of training AI agents will be accessible to non-technical experts. The only critical skill will be leveraging deep domain knowledge to identify where a model makes a mistake, opening a new career path for most knowledge workers.

Creating Benchmarks Is the True Bottleneck to Complex AI Capabilities

AI struggles with long-horizon tasks not just due to technical limits, but because we lack good ways to measure performance. Once effective evaluations (evals) for these capabilities exist, researchers can rapidly optimize models against them, accelerating progress significantly.

Dyslexia May Foster Entrepreneurial Success by Forcing Early Mastery of Delegation

The correlation between dyslexia and entrepreneurship may be because the condition forces individuals to master delegation from a young age. This early development of a crucial leadership skill provides an advantage over competent peers who often learn it much later in their careers.

Scoring Rubrics Are More Valuable for AI Training Than Raw Content

Data that measures success, like a grading rubric, is far more valuable for AI training than simple raw output. This 'second kind of data' enables iterative learning by allowing models to attempt a problem, receive a score, and learn from the feedback.

Future Knowledge Work Is Designing Reinforcement Learning Environments for AI Agents

Knowledge work will shift from performing repetitive tasks to teaching AI agents how to do them. Workers will identify agent mistakes and turn them into reinforcement learning (RL) environments, creating a high-leverage, fixed-cost asset similar to software.

AI Benchmarks Must Shift from Academic Puzzles to Economically Valuable Tasks

The most significant gap in AI research is its focus on academic evaluations instead of tasks customers value, like medical diagnosis or legal drafting. The solution is using real-world experts to define benchmarks that measure performance on economically relevant work.

AI Training on Subjective Skills Needs Graders Who Partially Disagree

To teach AI subjective skills like poetry, a group of experts with some disagreement is better than one with full consensus. This approach captures diverse tastes and edge cases, which is more valuable for creating a robust model than achieving perfect agreement.

AI Models Struggle Most with Uncodified 'Taste-Based' Expert Knowledge

AI performs poorly in areas where expertise is based on unwritten 'taste' or intuition rather than documented knowledge. If the correct approach doesn't exist in training data or isn't explicitly provided by human trainers, models will inevitably struggle with that particular problem.

Encourage AI Tool Use in Hiring Tests to Better Predict Job Performance

Rather than creating assessments that prohibit AI use, hiring managers should embrace it. A candidate's ability to leverage tools like ChatGPT to complete a project is a more accurate predictor of their future impact than their ability to perform tasks without them.

Proxy AI's Economic Value by Weighting Tasks by Expert Time Allocation

To measure an AI model's economic value, survey domain experts on how they allocate their time across various tasks. This time-allocation data serves as a proxy for the economic weight of each task, against which the model's performance can be scored.
