In manager meetings, CIO Collette Chilton intentionally avoids position-level discussions. Instead, she explores broader topics like life and current events to gauge the manager's mindset, while her team handles granular portfolio analysis, creating a dual-layered diligence process.

A core tenet of Collette Chilton's investment philosophy is the principle of explainability. If she cannot clearly articulate a manager's strategy and what could go wrong to her investment committee, she will not approve the investment, leading to a portfolio of understandable strategies.

Investment committees are adept at analyzing deal specifics like cash flow and competition. However, they systematically fail to discuss the more influential internal firm dynamics—such as pressure to deploy capital or individual biases—that are often the true cause of poor investment decisions and bad outcomes.

To improve decision-making, BlackRock's investment committee, guided by a behavioral scientist, uses autonomous voting to prevent peer pressure. It also mandates a non-voting "challenger" to play devil's advocate and champion a pre-mortem perspective, ensuring dissent is valued.

Great investment ideas are often idiosyncratic and contrary to conventional wisdom. A committee structure, which inherently seeks consensus and avoids career risk, is structurally incapable of approving such unconventional bets. To achieve superior results, talented investors must be freed from bureaucratic constraints that favor conformity.

Horowitz's steelman argument for small VC firms is that most firm structures are incompatible with scale. Partnerships with shared control can't make the hard decisions needed to reorganize. Furthermore, a single investment committee with 20 people destroys the candid, truth-seeking conversation essential for good investing.

When new managing directors joined Williams, the entire portfolio was re-underwritten to get them up to speed. This process provided a fresh perspective that revealed complacency and outdated narratives, even in areas the CIO had originally built, proving it a powerful tool for self-correction.

The romanticized idea of a dramatic "investment committee" meeting is a myth. The most effective investment process is collaborative and iterative, where an idea is pitched early and gains momentum across the firm over time. The formal meeting becomes a rubber stamp for a decision that has already been organically reached.

The Williams College investment team's strength lies in balancing deep institutional knowledge with fresh external perspectives. Long-tenured members provide historical context, while new hires from other offices introduce new best practices and challenge complacency, preventing stagnation.
