It only got more chaotic after that as everyone's arsenals were deployed... at one point I had a full 180 spin out and we had a head on collision take place.
Great fun, and we'll be playing again for sure.

Needless to say mayhem ensued... we had a stall on the start line and wrecks taking place immediately as the various ramming implements (e.g., the mechanical leg salvaged from a walker on my wagon) were put to use.

My friend had been long planning a game for "Orktober" and reskinned the game "Gaslands" where you have Mad Max style races to be a bit more... well, more Orky. So Daze of Funda was born! He also 3d printed us all the same chassis to use and we all kitbashed and kustomised our own Battlewagons.

Meanwhile, Joslyn collected new data from 8 participants in a crossover design. We analysed his data using the priors from the meta-analysis. The result? His study barely shifted the posterior beliefs — the prior and posterior distributions almost perfectly overlapped.

![A two-panel forest-style plot showing results from an empirical study comparing the effects of ammonia inhalants, placebo, and control conditions on Peak Force (left) and Rate of Force Development (right). The x-axis represents Standardised Mean Difference (SMD), with dotted vertical lines marking the null region (–0.1 to 0.1). Each panel displays posterior distributions (gray density shapes) with mean estimates, 95% quantile intervals, and 2×log(BF) values indicating Bayes factors relative to the null region.
Peak Force panel:
Placebo vs Control: SMD = –0.08 [–0.28, 0.11], 2×log(BF) = 0.26
Ammonia vs Placebo: SMD = 0.22 [–0.01, 0.47], 2×log(BF) = 1.06
Ammonia vs Control: SMD = 0.14 [0.01, 0.30], 2×log(BF) = 0.91
Rate of Force Development panel:
Placebo vs Control: SMD = –0.08 [–0.28, 0.10], 2×log(BF) = –0.33
Ammonia vs Placebo: SMD = 0.30 [0.09, 0.52], 2×log(BF) = –0.53
Ammonia vs Control: SMD = 0.22 [0.09, 0.35], 2×log(BF) = 0.02
A note below the panels explains that 2×log(BF) values indicate the strength of evidence against the null, following the Kass and Raftery (1995) interpretation scale:
Negative = evidence for the null,
0–2 = weak,
2–6 = positive,
6–10 = strong,
10 = very strong evidence for an effect.
Overall, the posterior distributions overlap substantially, suggesting minimal change in beliefs from the prior evidence.](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:evz2lw2i64j2p6qaawvfoohz/bafkreicl4mmfxkd626orcn5y2qf3imvb42jiraef75e66frvjkrvpx4yne@jpeg)

While most individual studies were mostly “null,” collectively they suggested small, possibly positive effects on some outcomes — though with modest precision.

![A three-panel forest-style plot showing results from a contrast-based network meta-analysis comparing the effects of ammonia inhalants, placebo, and control conditions on power, speed, and strength outcomes. Each panel (Power, Speed, Strength) shows standardized mean differences (SMDs) and 95% quantile intervals for each contrast (Placebo vs Control, Ammonia vs Placebo, Ammonia vs Control).
Power:
Placebo vs Control: SMD = –0.09 [–0.26, 0.09], Probability of null effect = 51%, meaningful effect = 2%.
Ammonia vs Placebo: SMD = 0.33 [0.19, 0.46], Probability of null = 0%, meaningful = 100%.
Ammonia vs Control: SMD = 0.23 [0.10, 0.38], Probability of null = 2%, meaningful = 98%.
Speed:
Placebo vs Control: SMD = 0.05 [–0.34, 0.45], Probability of null = 38%, meaningful = 41%.
Ammonia vs Placebo: SMD = 0.02 [–0.35, 0.40], Probability of null = 40%, meaningful = 34%.
Ammonia vs Control: SMD = 0.08 [–0.25, 0.40], Probability of null = 42%, meaningful = 44%.
Strength:
Placebo vs Control: SMD = –0.06 [–0.27, 0.15], Probability of null = 57%, meaningful = 6%.
Ammonia vs Placebo: SMD = 0.18 [0.01, 0.36], Probability of null = 19%, meaningful = 81%.
Ammonia vs Control: SMD = 0.12 [0.03, 0.28], Probability of null = 42%, meaningful = 57%.
Each panel shows posterior distributions as gray density shapes, centered around the estimated SMDs. Dotted vertical lines indicate the null region (–0.1 to 0.1). Text at the bottom notes that probabilities of null and meaningful effects were calculated as the proportion of posterior mass within or beyond this region, respectively.](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:evz2lw2i64j2p6qaawvfoohz/bafkreig6dy4k5zxoxsdi27kbxtpbleyysp27pivevv62rs7hayeai7u654@jpeg)

Certainly from a Meehlian perspective, and even considering it's essentially retrodictive, that would tend to provide further corroboration for the theory that trained folks just don't really grow much. Especially when combined with our estimates from the latest Project Discover.

So I went back and pulled out the data from these studies to take a look, and lo and behold the estimates weren't that far off what we'd expect... the confidence interval still contains zero, but the estimate is fairly close with the power/precision boost from pooling the data.

The x-axis is labeled “Standardised Mean Effect” ranging from approximately -0.25 to 1.00. A black point estimate with a narrow horizontal error bar is shown with the value 0.02 [95%CI: -0.01, 0.05] printed next to it, derived from individual participant-level modeling of previous studies (n=323). A much wider horizontal interval labeled “Spielraum” spans roughly -0.1 to 0.77, representing the 95% prediction interval from a large-scale meta-analysis. A shaded grey vertical band represents the predicted effect from theory ranging an interval of 0.042 to 0.057, indicating theory tolerance.

I guess I should add then... this is how I tend to try to practice science, and where pre-registration fits in for me i.e., the part where I make specific statistical claims based on tests conducted in particular operational contexts.

For example, here we have the range prediction from theory, the background range of effects observed in other studies absent the theory (Meehl's "spielraum"), and the estimates from the study... I wonder if it's maybe that instead from a Bayesian perspective the spielraum should be the prior?
