There was a post 2.65 years ago making the same point: Note on Terminology: “Rationality”, not “Rationalism”.
Back then, the confusion between these terms seemed more salient, but Google results count doesn’t support this impression (4.8% of “rationalism” in 2011 vs. 4.2% of “rationalism” in 2013). The result count from Jan 2011:
“rationality” − 3720 results
“rationalist” − 1210 results
“rationalism” − 251 results (4.8%)
Current results (Sep 2013):
“rationality” − 28400 results
“rationalist” − 3940 results
“rationalism” − 1410 results (4.2%)
