Psychological Maps 2.0 is a web-based project that aims to map London using social media data and citizen participation. By tracking tweets and having London residents play an online game to test their knowledge of different areas, the project seeks to better understand visibility, social deprivation, and subjective well-being across different London neighborhoods in a data-driven way. Over 2,000 people from varied demographics have already participated, providing insights into how visibility relates to factors like architecture, exposure in media, and socioeconomic status.
