Bayesian archaeomagnetic inversion is a method used to reconstruct past geomagnetic field behaviour from archaeomagnetic data by incorporating prior knowledge and quantifying uncertainty. It differs from traditional methods by providing a probability distribution of possible field models, rather than a single best-fit solution, which allows for a more robust assessment of the reliability of the results and the identification of potential biases.
