16Personalities vs Shikilux

16Personalities and Shikilux both offer “type-based maps for self-understanding,” but their starting points (self-report vs. birthdate) and dimensional structures (Big Five-derived 5 aspects vs. 4-axis structure) differ. This article compares the two across six aspects.

From Shikilux Editorial This article respects 16Personalities’ characteristics while clarifying differences and overlaps. The aim is “use in combination,” not ranking.

What 16Personalities is

16Personalities, offered by NERIS Analytics (UK) since 2011, is a self-understanding tool that extends MBTI’s four-axis structure by adding a factor from Big Five (five-factor model). It uses 5 aspects × 16 types (effectively 32 with Identity’s Assertive/Turbulent split). Freely accessible online, with over 400 million users reported as of 2024.

Main features:

• Input: ~60-question self-report
• Dimensions: 5 aspects (Energy / Mind / Nature / Tactics / Identity)
• Types: 16 (×2 with Identity)
• Calculation basis: Integration of Big Five and Jung type theory
• Cultural background: Modern personality statistics (Western)

16P incorporates more empirical validity from Big Five compared to MBTI; the addition of Turbulent / Assertive as a self-evaluation axis is distinctive.

What Shikilux is

Shikilux is an East-West integrative framework that supports self-understanding through four axes (Essence, Cycle, Relation, Compass) starting from a birthdate.

Main features:

• Input: Birthdate, optionally time and place
• Dimensions: 4 axes
• Types: 60 essence types × 12 cycle phases × 8 relation labels × 84 compass cells
• Calculation basis: Integration of Chinese sexagenary, Five Elements, Western astrology, psychological typology (implementation held as trade secret)
• Cultural background: East-West integration

Shikilux uses an objective input (birthdate) to avoid self-report cognitive biases. The 12-phase cycle axis also addresses the time-axis question “what phase am I in now?”

Which to choose

When 16Personalities fits

• Deep self-analysis through self-report: 60 questions
• Big Five empirical grounding: Aligned with NEO-PI-R and other Big Five tools
• Static type capture: Snapshot of current tendencies in one image
• Team allocation, coaching: Many coaches adopt 16P

When Shikilux fits

• Avoiding self-report bias: Objective calculation from birthdate
• Time axis (phases): Knowing whether you’re in “Seed,” “Bloom,” “Hibernation,” etc.
• Relational compatibility: 8 relation labels
• East-West perspective: Sexagenary, Five Elements, astrology, psychology on one map
• Practical guidance: Daily hints from 84 compass cells

Using both

The two are complementary.

• 16Personalities for self-report-based “current cognitive type”
• Shikilux for birthdate-based “essence + phase + relation + compass”

Where the two converge, a tendency is confirmed from multiple angles. Where they diverge, the gap between “self-report” and “objective input” surfaces self-perception distortions.

FAQ

Which is more accurate, 16P or Shikilux?

The two have different accuracy criteria. 16P emphasizes Big Five statistical validity; Shikilux emphasizes East-West integrative interpretive validity. Not a ranking — a matter of use.

Do 16P types map to Shikilux’s 60 types?

No direct 1-to-1 correspondence exists. The dimensions differ, so it’s better to hold both maps separately.

Does 16P’s Turbulent/Assertive correspond to anything in Shikilux?

Conceptually close to Shikilux’s “stable/changing” qualitative profile dimension. But calculation bases differ, so not identical.

What order should I use 16P and Shikilux?

No fixed order. Capturing essence and current phase first via Shikilux, then checking “current cognitive type” via 16P, makes self-perception distortions visible from the difference.

Why do 16P results change over time? Is that related to Shikilux?

16P results shift with mood, situation, experience — a feature of self-report tools. Shikilux’s cycle axis points to “what phase you’re in” as the background of that variation.

Can Shikilux replace 16P?

Not replace, but complement. Using both raises self-understanding resolution.

Is Shikilux divination, and 16P psychology?

Shikilux is designed as “a mirror, not an oracle” — a self-understanding tool. 16P is a psychological tool based on Big Five statistics. Shikilux integrates traditional divination elements (sexagenary, Five Elements) but its outputs are positioned as “tendency maps,” not predictions.
