The purpose of this document is to outline the main arguments and gather the supporting evidence collected so far. Each section below summarises one source and notes how it relates to the central question.
The first source provides useful background but is limited in scope. Its methodology is described only briefly, and the sample size is small enough that the conclusions should be treated as indicative rather than definitive.
The second source approaches the same question from a different angle and reaches a broadly similar conclusion. Taken together, the two suggest a pattern worth exploring further in the next draft.
Remaining work: expand the second section, add citations in the required format, and review the introduction once the argument is settled.
