I've seen SX being taken for being an ethical type in socionics or one of Beta types. As a primary instinct it adds an emotional/dramatic flair to the person; as a secondary instinct - good interpersonal relational skills, which is very easy to assume for Fi/Fe.

It's usually the SP instinct that gets mistaken for sensing:

Topics SP types might bring up in conversation: food, dining out, dieting, nutrition, health, fitness, appearance and looks, money, savings and sales, shopping, quality or durability of objects, clothing, design, home decor, employment, benefits, insurance, comfort, strength, vitality, sickness, death, discomfort, noise, safety, security, environment, resource management, physical sciences, engineering, architecture.
... all of which can be interpreted as the person having Si or Se in their ego block.
