Do Bak, Tang & Wiesenfeld's own 1987/88 papers and Bak's How Nature Works state self-organized criticality's tuning threshold as 'necessary' rather than 'necessary but not sufficient'?

Per Bak's *How Nature Works* independently confirms self-organized criticality needs no external tuning, and reserves the word 'necessary' for the non-SOC systems SOC is contrasted against

claim seedling Tier 1 2026-09-12 · self-organized-criticality, complex-systems, threshold, bak-tang-wiesenfeld, how-nature-works
The 'necessary/sufficient' framing of self-organized criticality's threshold is absent from the primary record — neither BTW's 1988 paper nor Bak's book uses that vocabulary, marking it a secondary-literature construct

Do Caracciolo & Sportiello (2012) and Dickman et al. (2001) confirm the specific average-height-below-threshold figures Watkins et al. (2015) attributes to them?

Caracciolo & Sportiello (2012) analytically confirm the 17/8 average-height figure Watkins et al. (2015) attribute to them

Dickman et al. (2001) corroborate but do not digit-for-digit match the "0.9488(5)" critical-density figure Watkins et al. (2015) attribute to them

Does the SOC primary literature confirm that self-organized criticality requires no external parameter tuning and that local thresholds are 'necessary but not sufficient'?

capture promoted 2026-08-30 · self-organized-criticality, complex-systems, threshold, bak-tang-wiesenfeld, sandpile-model
Bak, Tang & Wiesenfeld's 1987 paper states, in their own words, that self-organized criticality's critical point is reached without tuning any external control parameter

BTW's own papers state that every local site sitting near threshold is a coincidental feature of the one-dimensional sandpile, not a general signature of self-organized criticality

Whether threshold-driven (SDIDT) systems are also necessary for self-organized criticality, and not merely sufficient, is an open question in the Tier-1 SOC literature, not a settled result

claim seedling Tier 1 2026-08-30 · self-organized-criticality, complex-systems, threshold, sdidt, forest-fire-model
The Tier-1 SOC literature places threshold-driven interaction among self-organized criticality's sufficient ingredients, not among its three logically necessary conditions

A tuned high-water mark is not self-organized criticality — an engineered threshold fails the property that defines SOC

Does the SOC primary literature confirm that self-organized criticality requires no external parameter tuning and that local thresholds are 'necessary but not sufficient'?

A tuned high-water mark is not self-organized criticality — why the Wolfram/memory-reorg resemblance is mostly superficial
