Many mechanists have explored the strategies that scientists use in discovery. Bechtel and Richardson attended to decomposition and localization; Darden and Craver highlighted forward and backward chaining; Russo and Williamson emphasized drawing on both difference-making and mechanistic evidence. These strategies were found in specific, experimental sciences, such as neuroscience and molecular biology. So one task for philosophers moving forward is to assess whether or not similar strategies exist in other sciences, especially those that operate outside the traditional laboratory, both in the human sciences (such as sociology and economics) and in the physical sciences (such as cosmology).
