浅はか (asahaka) implies a lack of depth in judgment or foresight, often with a negative moral tinge. 表面的 (hyōmenteki) is more neutral and simply means 'on the surface', without necessarily implying foolishness. Use 浅はか for criticizing shallow thinking, and 表面的 for describing surface-level analysis.
Directly translating 'superficial way of thinking' as 表面的な考え方 is acceptable, but in many contexts, 浅はかな考え or 甘い考え sound more natural and idiomatic. Choose based on the nuance you want to convey.
