> Researchers found that those who downloaded "free" music – whether from lawful or seedy sources – were also 10 times more likely to pay for music. 10 times more likely to pay for music they've acquired, or 10 times more likely to buy music, period? More explicit data is needed. Example: The pirates acquire 10000 songs; pay for 100 of them (1%). The non-pirates acquire 10 songs, pay for 10 (100%). "The pirates have paid for ten times as many as the non pirates." But the results can swing the other way: Example: The pirates acquire 100 songs, pay for 1 of them (same 1%). Non-pirates acquire 10, pay for 10 (same 100%). Suddenly: "The non-pirates have paid for ten times as many as the pirates." So, simply by getting more pirate respondents to participate in your study, you can manipulate the result increasingly in favour of piracy. We need to see the data to be able to determine whether they really corroborate the conclusion.
