[Christmas article: The ideal Christmas gift - a randomised crossover study]

The joy of Christmas gifts depends not only on their content but also on how they're presented. We investigated which gift characteristics most effectively increase recipient joy.

We conducted a randomised, placebo-controlled, crossover trial. 31 adults aged 21-66 years each evaluated 27 gifts differing in wrapping, size, weight, texture, and accompanying narratives. Recipient joy was rated on a Christmas-modified 0-10 Wong-Baker scale.

Median self-reported enjoyment of Christmas was eight on a 0-10 scale (IQR 6-9). Compared with a red-wrapped reference gift, several factors significantly increased joy: gold wrapping paper (+1.48), a bow (+1.81), softness (+1.90), the sound of broken porcelain (+2.61), and especially a long, heartfelt card (+5.42). Larger (+3.55) and heavier (+3.48) gifts were better received than smaller or lighter ones. Verbal stories describing the gift as "expensive" (+3.19) or "hard to find" (+3.23) also enhanced ratings. From a cost-effectiveness perspective, small gifts paired with a brief narrative offered the highest joy per unit of time and material. In a separate comparison, identically wrapped gifts containing either a gift card worth DKK 500 or a 10 mL saline syringe yielded different outcomes: the placebo gift scored significantly higher (6.90 vs. 5.03; p=0.005).

To maximise Christmas joy, the gift should be large, heavy, soft, wrapped in gold paper with a bow, and accompanied by a long, heartfelt card and a convincing backstory.
