Seek out any written or transcribed communication they have made public on social media or websites. Twitter is a good source to find a person’s thoughts and opinions which are written in a conversational tone. Be careful of getting data from LinkedIn profiles which are often written by third parties and not in the speaker’s own natural language. Video blogs and YouTube videos are often transcribed and offer large samples which are unrehearsed or unscripted. Running these samples through the First Impressions tool will yield highly accurate insights.
