The author notes that there is evidence that models of memory intended to be general have taken insufficient account of findings from olfaction and other sensory modalities, an approach that could be considered symptomatic of dangerous tendency to base purportedly general theories on databases that are too narrow.
This Is Why We Associate Memories So Strongly With Specific Smells Smell is believed to be closely tied to memory because of our olfactory system's processing speed and proximity to the limbic system. The author notes that there is evidence that models of memory intended to be general have taken insufficient account of findings from olfaction and other sensory modalities, an approach that could be considered symptomatic of dangerous tendency to base purportedly general theories on databases that are too narrow.
