The default philosophical position for human biology and psychology is known as Representational Realism. That is, reality as we know it is mediated by changes and transformations made to sensory (and other) input data in a complex process, and is changed sufficiently to be something "different enough" from what we know to be actually real.

Direct Realism is the idea that reality is directly available to us and any intermediate transformations made by our brains is not enough to change the dial.

Direct Realism has long been refuted. There are a number of examples, e.g. the hot and cold bucket; the straw in a glass; rainbows and other epiphenomena, etc.
