When you'd hear it
This is neutral and appears in everyday conversation, personal explanations, and informal writing. Speakers use it when connecting an observed result with a possible cause, without sounding fully certain.
What learners get wrong
Unlike -아/어서, which usually presents a cause more directly, -아/어서인지 marks the cause as a guess. Compare 열심히 공부해서 좋은 성적을 받아요 (because I study hard) with 열심히 공부해서인지 좋은 성적을 받아요 (perhaps because I study hard).
