The emote "¯\_(⊜‿⊜)_/¯" is typically used to express a sense of confusion, uncertainty, or indifference. It can also be interpreted as a shrug of the shoulders and often implies that the person using it doesn't know the answer or doesn't have a strong opinion on the matter. The "Should I know?" emote is not a commonly recognized emote, but it could potentially be used to convey a similar sentiment of uncertainty or lack of knowledge.
