The position is a form of anti-realism: Anti-realism states that there is no objective reality independent of our sense data (so a strong form of empiricism), the only thing we can know is our own observations. Anti-realism is a broad position which can be applied to science, math, metaphysics, etc..When applying it to science, it means that things such as waves, atoms and sub-atomic particles, genes, etc don't exist other than convenient ways to helps predict our sense data. To some extent, the logical positivists were anti-realists.
It can also be seen as a form of pragmatism: we will never know the ultimate nature of reality and being, blah, blah, blah,...our theories are good as long as they are useful and have "cash-value". Pragmatism when applied to science became known as instrumentalism, and was championed by John Dewey.
