inaction dominates — Inaction dominates — most regret not acting.
In a prospective study of 576 families whose children had their tonsils removed for recurrent throat infections, 91% of parents were satisfied with the benefit one year later, and febrile sore-throat episodes fell from a mean of 6.7 in the year before surgery to 1.5 in the year after (Wolfensberger et al., 2000). Direct measurement with the validated Decision Regret Scale tells the same story from the other direction: among 102 families, median decisional regret after tonsillectomy was 0 (Carr et al., 2016), with the regret that did exist concentrated among parents who had entered the decision conflicted. For the typical family that proceeds, action regret is low — roughly the 9% who were not satisfied with the result.
The waiting side carries more documented hindsight regret. In the same 576-family cohort, 28% of parents regretted not having arranged the surgery earlier — a wish, in retrospect, that they had stopped waiting sooner. This is the inaction-regret proxy, and it must be read with care: it is measured among parents who ultimately operated, not among families who declined surgery and kept the tonsils, because no survey directly asks the watchful-waiting group whether they regret that choice. The AHRQ-supported systematic review (Morad et al., 2017) explains the structural reason the asymmetry runs this way: surgery produces a real but modest reduction in throat infections in the first year that does not persist, while most children improve with age regardless. The regretted cost of waiting is therefore the year or two of continued illness, not a permanent loss.
The pattern fits Gilovich and Medvec’s temporal asymmetry: the parents who acted overwhelmingly judge the outcome positively, while a larger share of those who delayed wish they had moved sooner. The honest limits are real. Both proxy rates come from a single surgical cohort, the action figure is dissatisfaction rather than regret, and tonsillectomy carries genuine surgical risk — post-operative bleeding and anaesthetic complications — that satisfaction surveys understate. Current guidelines (AAO-HNS, 2019) deliberately frame the benefit as “modest” against the natural history of resolution. What the data establish is a direction, not a precise gap: among families facing recurrent throat infection, the decision to wait generates more retrospective regret than the decision to operate, even though for most children the difference fades within a couple of years.

Peer-reviewed
524 of 576 parents (91%) satisfied with the benefit one year after surgery; febrile sore throat episodes fell from a mean of 6.7 to 1.5 per year
Excerpt
“"[Paraphrase from abstract — full text paywalled] Of 664 children enrolled, 576 parents returned the follow-up questionnaire (87%). 524 parents (91%) were satisfied with the benefit. The number of episodes of febrile sore throat dropped from a mean of 6.7 in the year prior to surgery to a mean of 1.5 in the year after surgery (P<0.001). 88% of the (adeno-)tonsillectomies were performed because of documented recurrent febrile tonsillitis or obstructive symptoms."

Prospective multicenter study; 576 of 664 enrolled families returned the 1-year questionnaire. 91% satisfied implies ~9% not satisfied with the benefit, which we use as the action-side regret proxy. This is a dissatisfaction measure, not the word "regret"; it is the closest directly-quantified action-side signal in a recurrent-infection population. European (Zurich) cohort.

Among 102 families, median decisional regret was 0 (mean 8.78 on the 0–100 Decision Regret Scale); regret was higher in parents who had decisional conflict (20.00 vs 7.59; P<.05)
Excerpt
“"[Paraphrase from abstract — full text paywalled] A total of 102 families were studied (mean child age 6.29 years). Median decisional regret was 0 (mean 8.78); median decisional conflict was 0 (mean 7.74). Decisional regret was significantly higher in parents who reported decisional conflict (20.00 vs 7.59; P<.05). Decisional conflict was higher in parents who cancelled surgery or failed to keep follow-up appointments (27.19) than in parents who brought their children for surgery (6.78; P<.05)."

Direct Decision Regret Scale measurement (validated Brehaut DRS, 0–100). Median 0 confirms decisional regret after tonsillectomy is low for most parents and concentrated among those who entered the decision conflicted. Corroborates the ~9% dissatisfaction figure: the action side carries low regret for the typical parent.

This 28% is the inaction-regret proxy: parents wishing, in hindsight, that they had acted sooner rather than waited. Construct caveat — it is measured among parents who ultimately had surgery (regret of the waiting period), not among a watchful-waiting cohort that never operated. No survey directly asks parents who declined surgery whether they regret keeping the tonsils. Both action and inaction figures come from the same surgical population; the asymmetry (9% vs 28%) is the defensible signal, not the precise magnitude.
[2]Pediatrics (Morad et al. 2017, AHRQ-supported review) — Tonsillectomy Versus Watchful Waiting for Recurrent Throat Infection: A Systematic Review
Peer-reviewed
Greater short-term (<12 months) reduction in sore throats and streptococcal infections with surgery vs watchful waiting (moderate strength of evidence); benefits did not persist over time
Excerpt
“"In all studies reporting baseline data, number of infections decreased from baseline in both groups, with significantly greater decreases in sore throat days and diagnosed GAS infections in children who received tonsillectomy versus no surgery/watchful waiting. ... These benefits did not persist over time. ... We have greater confidence that compared with no surgery, tonsillectomy reduced sore throats/throat infections or streptococcal infections in the short term (<12 months; moderate SOE)."

Calculation
AHRQ-supported systematic review (published in Pediatrics). Establishes that watchful waiting carries a real but modest short-term cost (more sore-throat days in the first year) that resolves over time as most children improve regardless of surgery. This is the outcome anchor underpinning the inaction-regret proxy: the cost of waiting is concentrated in the year or two of continued infections, after which the natural-history advantage of surgery fades. Used for direction, not for a regret percentage.
Caveats
Both rates are proxies drawn from the same prospective cohort of parents whose children ultimately had surgery (Wolfensberger 2000, n=576, Zurich). The action-side 9% is a dissatisfaction-with-benefit rate, not a direct regret measure; the Carr 2016 Decision Regret Scale study (n=102, US) confirms that direct decisional regret after tonsillectomy is low (median 0) and concentrated among parents who entered the decision conflicted. The inaction-side 28% measures parents who, after surgery, regretted not arranging it earlier — a retrospective wish-they-had-acted-sooner signal, not a regret rate among parents who declined surgery and kept the tonsils. No published survey directly asks watchful-waiting families whether they regret keeping the tonsils, so the true inaction-regret rate is unknown. The AHRQ systematic review (Morad 2017) confirms the structural reason the asymmetry points this way: surgery delivers a real but modest short-term reduction in throat infections that does not persist, while most children improve with age regardless — so the regretted cost of waiting is the year or two of continued illness, not a permanent loss. Modern guidelines (AAO-HNS 2019) advise that families be counselled on "only modest anticipated benefits" weighed against surgical risk. The -0.19 delta should be read as an indicative direction (inaction generates more documented retrospective regret than action), consistent with Gilovich and Medvec's temporal-asymmetry framework, not as a precise population estimate. Tonsillectomy carries real surgical risk (post-operative haemorrhage, anaesthetic risk) that the satisfaction figures do not fully capture.
