Revise Identity, expression and space online for IB Digital Society (1.2)

Your online identity is the version of you that exists in digital spaces. Unlike a fixed offline identity, it is often highly curated—we consciously select photos, share specific achievements, and craft posts to present an idealised version of ourselves. Individuals may also manage multiple identities, such as a professional LinkedIn profile, a pseudonymous gaming handle, and an anonymous account on a forum for discussing sensitive topics. This fragmentation can be empowering but also leads to 'context collapse', where these different audiences and identities unintentionally merge, sometimes with awkward or negative consequences.

Digital platforms are not neutral conduits for communication. Their design, or 'architecture', fundamentally shapes how we can express ourselves. These design features are known as 'affordances'. For example, the original 140-character limit on Twitter afforded concise, punchy statements, while TikTok's video-centric format affords performance, dance, and visual storytelling. Furthermore, what we see is not random; it is governed by algorithmic curation, which prioritises content likely to maximise our engagement. This means our expression is often a response to what the platform's algorithm values, not just what we authentically wish to say.

The algorithmic curation that powers our feeds has significant societal consequences. It can lead to the formation of 'filter bubbles', where we are unknowingly isolated from information and perspectives that contradict our own. The algorithm learns what we like and shows us more of the same, creating a personalised reality. This is often compounded by 'echo chambers', where we actively choose to connect with like-minded individuals, and our beliefs are reinforced and amplified by the group. The combination of these two phenomena can increase political polarisation, hinder mutual understanding, and accelerate the spread of misinformation within insulated communities.
