This &quot;study&quot; isn&#x27;t a study at all. One week provides factually meaningless data. You&#x27;d need a minimum of 3 months just to register a new baseline, and another 6-12 months to see if those participants who originally found a higher baseline at 3 months maintain it or fall back to previous levels as the novelty of the situation wears off.<p>You want to know why people reported feeling better? Because they changed a habit. When you change <i>anything</i> in your life for a single week, you will feel better because you have pulled yourself out of your everyday routine and are experiencing something NEW. This is the result of a change; what changed - Facebook in this case - does not matter.<p>The novelty of a change in habit for a single week does not even begin to offer evidence of anything. This isn&#x27;t even a case of &quot;not enough evidence&quot;, but rather &quot;no evidence whatsoever&quot;. This novelty is similar to the kind of high you get from buying a new expensive toy&#x2F;gadget. A temporary boost of &quot;happiness&quot; that quickly fades as the new item just becomes another object in your day-to-day life.
