In learning, repetition is key in order to ingrain new information into our memory so that we can recall it later when we need it. Successful replication provides evidence of generalizability across the conditions that inevitably differ from the original study; unsuccessful replication indicates that the reliability of the finding may be more constrained than recognized previously.

Those different results give us a chance to discover more about our idea. It is always possible that it was real, and we cannot identify or recreate the conditions necessary to replicate successfully. The variability between measurements taken at the same factor settings tends to be greater for replicates than for repeats because the machines are reset before each run, adding more variability to the process.
