Anderson's Circle
The founders, investors, and thinkers who Anderson invested in, learned from, or whose thinking shaped the Scottish Mortgage philosophy.
James Anderson
The subject of this knowledge base — the investor whose philosophy it documents
James Anderson joined Baillie Gifford in 1983 after a history degree at Oxford and a year at Johns Hopkins in Bologna, and went on to manage Scottish Mortgage Investment Trust for over two decades (2000–2022). He transformed the trust from a conventional global equity vehicle into the most prominent public-market expression of extreme long-term investing: concentrated positions in transformative founder-led companies — Amazon, Tesla, Alibaba, Illumina, Moderna — held through violent drawdowns on horizons measured in decades. His intellectual framework, built on power-law return distributions, a Popperian refusal to forecast, and the conviction that imagination is the scarcest analytical resource, made Scottish Mortgage the UK's largest investment trust. He retired from Baillie Gifford in 2022, declaring in his final review that his greatest failing had been to be 'insufficiently radical', and joined Lingotto, the Agnelli family investment house, to continue the experiment with even longer horizons.

Paradigmatic example of the transformative founder Anderson sought — Amazon was Scottish Mortgage's defining holding
Anderson made Amazon one of Scottish Mortgage's largest positions before 2010, when the consensus view was that it was a low-margin retailer in a commodity business. His conviction that Bezos was building an exponential platform — not a retailer — was central to Scottish Mortgage's extraordinary returns over the following decade. Anderson has cited Amazon as the clearest real-world demonstration of how power-law dynamics operate: a company that looked absurdly expensive on every conventional metric became one of the greatest compounders in stock market history.

A defining investment — Scottish Mortgage was an early and high-conviction Tesla shareholder
Anderson saw Tesla not as a car company but as an energy and technology company pursuing exponential learning curves in battery technology and autonomous systems. Scottish Mortgage held Tesla through multiple near-bankruptcy episodes and was rewarded with returns that transformed the trust's performance. Anderson has described Musk as the clearest living embodiment of the kind of 'ambitious impossibilism' he looks for in founders — the willingness to pursue goals that conventional analysis declares impossible.

Successor and co-manager from 2015; took over leadership of Scottish Mortgage in 2022
Anderson gradually transitioned management of Scottish Mortgage to Tom Slater over the latter part of his tenure at Baillie Gifford. Slater joined the trust as deputy manager in 2015 and became lead manager when Anderson retired in 2022. Anderson has spoken warmly about Slater's ability to extend the investment philosophy into new areas — particularly private companies and the emerging generation of transformative technology platforms.
Profile →Founder, Templeton Funds; Pioneer of global investingSir John Templeton
The investor Anderson has cited most often as a philosophical predecessor
Anderson frequently invokes Templeton as the template for the kind of long-horizon, geographically uninhibited, and intellectually humble investing he practiced at Scottish Mortgage. Templeton pioneered global investing when it was deeply unfashionable and built a fortune by buying into maximum pessimism. Anderson sees in Templeton a kindred refusal to be constrained by consensus benchmarks, conventional valuations, or the intellectual comfort of home-country bias.
Profile →Philosopher; Author of The Logic of Scientific Discovery and The Open Society and Its EnemiesKarl Popper
Philosophical foundation for Anderson's epistemology — particularly his skepticism of forecasting
Anderson has explicitly cited Popper's epistemology as the philosophical basis of his investing approach. Popper argued that knowledge advances through conjecture and refutation, not through positive confirmation — and that any system claiming to predict the future with certainty is engaging in pseudo-science. For Anderson, this translates to a principled refusal to make precise earnings or price forecasts, and instead to focus on identifying companies whose range of possible outcomes includes transformative success, then letting time and compounding do the work.
