Final answer:
Steven would write truthfully and privately in a diary or journal, as these are meant for personal reflection and not public consumption.
Step-by-step explanation:
Steven writes truthfully and privately in a diary or a journal. Both are personal spaces where individuals can express themselves honestly without the expectation that others will see what they've written. This differs from a blog or social media, which are typically public or semi-public platforms where content is shared with others. The nature of diaries and journals as private mediums aligns with the need for veridical and truthful expression, where the writer is able to reflect accurately on their own experiences without the influence of external audiences.
