“A before-and-after slideshow hook you can use to promote a finance app - it opens on a reaction selfie, then contrasts a tiny starting balance with a massive future portfolio screenshot.”

This slideshow TikTok post pulled 18K views - 4× what the account typically does (~4.5K views on a normal post). That gap is what Handler calls an outlier: the breakout came from the content's structure, not the account's size.
