- Fixing a cloying oversight in my last forecast, which inexplicably--and in any case, mistakenly--recorded a 1% probability to >1800 cases (i.e., bin 5).
- For reasons laid out in my last forecast, I had assigned a (rounded-up) 100% probability to bin 3 (i.e., to cumulative cases between 1500 and 1649).
- The issue is now essentially already resolved, with CDC currently reporting 1514 cases. Judging especially from historical CDC data, there is no plausible reason to entertain the possibility, in the space of a week, of a potential surge in cases large enough to land us in bin 4 (let alone bin 5). But let the record reflect: I'm not cheating by tweaking my distribution, which now accurately reflects the 100% analysis of my (intended) previous forecast.
- Thank you ctsats for catching my error!

Star Commenter - Sep 2025
Why do you think you're right?
Why might you be wrong?
- The most likely error source, at this late juncture, would be new and/or corrected CDC data showing a greater number of cases than previously realized. Certainly not impossible.
Why do you think you're right?
- Updating/downgrading forecast to less than 0.5% probability, rounded down to zero. As with my just-filed adjusted forecast on India-Pakistan, there is no evident reason to expect such a scenario at this time, especially not at this time, in the still-warm afterglow of Xi-Modi summitry.
- I arrived at < 0.5% odds given (a) low base rate, (b) approaching deadline, and (c) influence of recent high-level diplomacy. The odds such a trend-defying scenario could unfold within the next 10 days are vanishingly small.
Why might you be wrong?
- I have no inside perspective. There are potentially latent Sino-Indian flashpoints--e.g., between patrolling aircraft, ships at sea, or border troops--where an unplanned or unforeseeable incident could get out of hand. As dltrybula notes, it only takes one person.
Why do you think you're right?
Doh! I just filed an updated forecast...and forgot to adjust my numbers on the board. I'm doing so now, for reasons just explained.
Why might you be wrong?
As noted in previous forecast filed moments ago.
Why do you think you're right?
- Updating/downgrading forecast to less than 0.5% probability, rounded down to zero. With no plausible evident predicate to anticipate an outbreak of hostilities--Pakistan's recent signing of a defense pact with Saudi Arabia isn't one, imho--there is vanishingly little time before deadline for (a) something to happen that (b) triggered hostilities that (c) produced 100+ casualties.
- I continue to assess that the most plausible trigger would be a major terrorist attack, whose incidence makes for a low base rate. I further assess that the chain of events from attack to hostilities to 100+ casualties would take at least several days to unfold. Which by implication means that a triggering terrorist incident big enough to produce a criteria-satisfying outcome would need to happen in the next few days. The odds of such a development on such a timeline are surely below 1%--and imho below even 0.5%.
Why might you be wrong?
- I have no expertise or inside perspective. For all I know, Modi might already be planning to drop the big one on Pakistan next week (to commemorate autumn equinox, or the first day of Durga Puja).
- More realistically, there's no assurance a major terrorist attack couldn't happen tomorrow--or even later today--and that the scale of a single retaliatory Indian strike on a Pakistani target couldn't produce 100+ casualties.
Why do you think you're right?
Adjusting forecast, now rounded down to zero percent. With less than 7 business days remaining before deadline and US military and civilian leadership seemingly focused on issues unrelated to ROK, I assess the odds of an announcement by 30 September to be less than 0.5%
Why might you be wrong?
As noted before, this administration can surprise. I continue to expect such a withdrawal/redeployment eventually will happen at some point in DJT's second term.
Why do you think you're right?
Belatedly moving my forecast to 100% on same reasoning ScottEastman convincingly offers in his updated forecast today. The odds of two Cat 3 landfalls within the next two weeks, while not impossible, appear so low as to, in effect, round down to zero.
Why might you be wrong?
I could be wrong in either of two ways:
- Black swan 1-2 combination on circa %0.1 odds.
- Odds are exactly zero at this point, on, e.g., meteorological grounds beyond my expertise. In which case the root error would be breathing any life whatsoever into an impossibility.
Why do you think you're right?
- Adjusting downward my last forecast, based on VTC yesterday with three RFI team members, one of whom (Scott Eastman) usefully pointed out that, even if the next Atlantic tropical depression (AL91) turns into a major hurricane, it would not likely make landfall (if at all) before circa 20 September, i.e. 10 days before deadline.
- AL91 is the only tropical depression currently observed between Africa and the Americas as of 6 September, and NOAA accords it only a 20% probability of cyclonic formation within 7 days.
- The odds, therefore, that a second major hurricane would materialize and hit the US within 10 days of a first, major landfalling hurricane--if indeed AL91 were to even become one--are extremely small, judging from historical NOAA data. I accord generous 4% odds only because experts are forecasting an above-average hurricane season and September is historically an active month. However unlikely, it could theoretically happen.
- By way of comparison, 4% odds are slightly better than my chances of getting into Harvard, judging by 2025 acceptance data. (Same rationale: unlikely, but could theoretically happen.)
Why might you be wrong?
- If anything, 4% odds of a second qualifying hurricane by 30 September are too generous. I suspect that, when I revisit this forecast in a week, I will reduce it by half or more.
- On the other hand, lacking relevant substantive expertise, I might be under-estimating the chances of another storm (or storms) developing within the next 10 days.
Why do you think you're right?
- This is a downward revision to my initial forecast in early June, capturing significantly greater-than-expected EU progress in reducing dependency on Russia for gas than I anticipated from their performance to date.
- At current levels of LNG and especially pipeline gas deliveries, it's looks extremely unlikely that total deliveries for any quarter this year could reach 15 bcm. The combination of EU commitments to end Russian energy dependency, the development of alternative supply infrastructure, and the deterioration of EU-RF relations creates significant barriers to restoring historical trade volumes.
- I accord a slightly higher alternative probability than the crowd (2% versus 1%) to capture the (admittedly small) possibility that a diplomatic breakthrough over Ukraine in the near future could alter the gas picture and enable, in turn, the possibility of 15 bpm in 4Q 2025. Remote, yes; impossible, no.
Why might you be wrong?
- If I'm wrong, it most likely would be because my forecast is too conservative. Perhaps there virtually no chance that 15bcm deliveries will happen any quarter in 2025.
- Even if I'm right, I could be wrong in assuming that the crowd forecast doesn't already factor for the possibility of a breakthrough over Ukraine.
