What Tone Should a Professional Bio Use?

Tone depends on platform and audience. LinkedIn and resume bios lean professional but can have warmth—avoid sounding like a robot. Social bios (Twitter, Instagram) allow more personality and informality. Speaker and author bios stay professional and credential-focused. Match your industry: finance and legal tend formal; creative and tech can be more relaxed. Avoid arrogance (let achievements speak) and excessive modesty (you're not underselling). The best tone is confident, clear, and human.
