Summary
Top1000funds.com has published an opinion piece by Paul Craven titled "Fight 'halo effect' and other biases." The publicly available excerpt opens with a general observation about the human brain and then directs readers to the full article, which is restricted to subscribers of the publication's institutional investment platform. The article is categorised under behavioural economics, biases and decision-making.

The halo effect refers to the tendency for an overall positive impression of a person, company or manager to colour judgments about their specific attributes or performance. For institutional investors, such effects can influence manager selection, due diligence and the interpretation of track records. The title indicates the column addresses this bias along with other cognitive distortions that can affect investment decisions. Because only the headline and introductory lines are accessible, the specific examples, data and recommendations in the piece cannot be detailed here.

The same page lists recent opinion columns from the WTW Thinking Ahead Institute on risk management, including pieces on 'risk 2.0' frameworks, interconnected risk mindsets and qualitative risk measures. These are separate contributions and are not part of Craven's article, but they reflect the publication's ongoing focus on how investors process risk and information.
