Criticism of use of mathematical models
A consistent topic in Orrell’s work is the limitations of mathematical models, and the need to acknowledge these limitations if we are to understand the causes of forecast error. He argues for example that errors in weather prediction are caused primarily by model error, rather than the butterfly effect. Economic models are seen as particularly unrealistic. In Truth or Beauty: Science and the Quest for Order, he suggests that many such theories, along with areas of physics such as string theory, are motivated largely by the desire to conform with a traditional scientific aesthetic, that is currently being subverted by developments in complexity science.

Quantum theory of money and value
Orrell is considered a leading proponent of quantum finance and quantum economics. In The Evolution of Money (coauthored with journalist Roman Chlupatý) and a series of articles he proposed a quantum theory of money and value, which states that money has dualistic properties because it combines the properties of an owned and valued thing, with those of abstract number. The fact that these two sides of money are incompatible leads to its complex and often unpredictable behavior. In Quantum Economics: The New Science of Money he argued that these dualistic properties feed up to affect the economy as a whole.
