Solid waste has mean (0.624) > max (0.525)
❌ Error 2 (level: MEDIUM)
Solid waste and fiscal revenue have SD > range/2
0.53 > (0.525-0.1)/2 = 0.2125
0.926 > (1.2-0.024)/2 = 0.588

Today is a day ending in "y", which means I found another mathematically-impossible Table of Summary Statistics in a peer-reviewed "green economics" paper!
What can you see? 🔎

god knows how that happened. but the lesson, as ever, is ABP (Always Be Plotting)
plot your raw data. plot your summary statistics. plot your model coefficients. plot your enemy's downfall. plot your residuals.

Ridiculously inaccurate summary stats feels like the research equivalent.
😂
Can you see the problem?

* SD values appear in Min column (or at least, these values = sqrt(var))

Dear academic papermills: for the low, low price of $9,999 (bitcoin only) I will check your tables of summary statistics before publication using my proprietary technology (lean back, squint at numbers for 90 seconds). DM for details.

Hats off.

In 2000s, Narayan develops a formula: add "nexus" to a classic econ literature about 2 vars
In 2010s, "nexus" independently becomes a policy buzzword ("Water-Energy-Food Nexus")
Papermills love to combine trendy words + topics
Result: 1000s of green econ "nexus" papers, esp 2021-24

I call it: "The "Nexus" Nexus" 😅
Recipe
🟢 Pick 1 econ var
🟢 Pick 2+ "green" vars
🟢 Pick 3+ methods (unit root, cointegration, Granger causality, GMM, ECM, FMOLS, PMG, PVAR, wavelet)
🟢 Misinterpret results
🟢 Make absurd policy recommendations
Rinse & repeat!

Can you guess the original phrase?
(e.g. "cloudiness contamination" ➡️ "air pollution")
1️⃣ carbon discharges
2️⃣ refillable energy
3️⃣ depressing influence
4️⃣ activist liaison
"Bosom peril" for "breast cancer" is an all-timer.
The best one I've personally found was a statistical method being described as "vigorous" (instead of "robust").
