経験 and 経歴: Lived experience and a presented history
Compare experience applied to work, including the possible value of failure, with a history summarized in an application or presented in a guidebook.
What was experienced and how it was used
経験 means experience. 「海外で暮らした経験を仕事に生かした。」 says experience of living abroad was applied to work. Read the experience and the activity to which it was applied.
「失敗も大切な経験になることがある。」 says even failure can become a valuable experience. ことがある gives a possibility, not a rule that every failure is necessarily valuable.
A history presented in documents
経歴 means career history or background. 「応募書類にはこれまでの経歴を簡潔にまとめた。」 says the speaker summarized their career history concisely in application documents.
「講師の詳しい経歴が案内冊子に載っている。」 states that the instructor’s detailed background appears in a guidebook. Summarizing or publishing a history does not describe acquiring a new experience at that time.
Experienced content and a selected account
経験 concerns what someone has lived through and where it is put to use. 経歴 concerns the history presented in an account or introduction. A concise history need not contain every experience.
Failure can also be an experience, so the word is not limited to successful events. A detailed background does not by itself quantify all ability, expertise, or successes.
Does a concise account of 経歴 in an application establish that it includes every 経験 the person has had?
Show the answer and why
No. 経歴 is the history presented in the document, while 経験 concerns what the person has experienced. A concise account does not state that every experience is included.
