This is true for most cases, because thin airfoils normally produce less drag and less lift than thick ones at the same angle of attack. But they are also exceptions. Thick airfoils, to be specific Supercritical airfoil, are commonly used by commercial airliners, but not only because they could produce less drag. cute pajamas sets for womenhttp://aero-comlab.stanford.edu/aa200b/lect_notes/lect3-4.pdf cute panda background

"Web20 Jan 2005 · The idea of thin airfoil theory is to use these expressions directly for ﬁnite-but-small angle changes imposed on the incoming ﬂow by airfoil surface shapes and angle of attack. Thus, if the airfoil is thin enough and the angle of attack is small enough, one may expect to be able to approximate ﬂow 4. " - Thin aerofoil theory
