Baseball Card System (for People)

Dalio's Baseball Cards summarize assessed strengths, weaknesses, and supporting observations to inform collaboration and role decisions. The assessments remain fallible and context-dependent even when quantified or algorithmically combined.

Dalio's Baseball Cards summarize a person's assessed strengths, weaknesses, and supporting evidence so that collaborators can consider relevant capabilities. In his account of Bridgewater, these profiles draw on multiple sources of observations and assessment. The central planning move is to ask what evidence bears on a specific role or judgment rather than letting a general impression substitute for task-relevant information.

A profile remains an interpretation built from selected opportunities, observations, and criteria. It does not become objective simply because it has numbers or an algorithm. Use transparent, bounded, revisable assessments with the affected people's participation, and distinguish demonstrated performance from missing evidence. A person may be capable but untested, improving, or performing under constraints the profile does not capture. The tool should support decisions without fixing identity or worth.

When to use it

When a team needs a shared, revisable account of relevant skills for collaboration, development, or role allocation.

How it can help

Use transparent, task-relevant evidence and allow participation, correction, and updating. Distinguish untested capability from poor performance and avoid broad personal verdicts.
