All three mean lacking depth, but for different things. Shallow judges a person's character or mind as lacking depth; blunt and informal. Slick describes talk or style as polished and impressive but empty underneath. Superficial describes an analysis covering only the obvious surface, missing details.

这三个词在此义项上都表示“缺乏深度或实质内容”，但侧重点不同：shallow多用于直接评价一个人的性格或思想，slick多用于形容表演、风格或说话方式华丽好看却空洞，superficial则多用于形容分析、理解等只停留在表面。这里不比较shallow的“（水等）浅的”义，不比较slick的“光滑的；圆滑老练的”义，也不比较superficial的“表面的（如伤口）”义。
