Established biomarkers, such as vocal acoustic properties and autonomic nervous system metrics, provide an objective baseline of stress and recovery states. Meanwhile, contested somatic methods are held to rigorous, double-blind testing standards to determine if they yield signals beyond expectancy and ideomotor effects. Every evaluation is conducted under a pre-registered, blinded framework, with all raw data and analysis code published openly to verify whether the interventions produce repeatable, measurable results.
establishedVoice and acoustic analytics
Voice and acoustic analytics provide an objective, non-invasive readout of physiological and emotional states. The larynx is innervated by the vagus nerve, establishing a direct anatomical link between autonomic nervous system activity and vocal cord tension. Consequently, emotional or physiological stress shifts autonomic activity, which measurably modulates vocal acoustics, affecting parameters such as jitter, shimmer, prosody, intonation, tonality, and pauses.
Evidence FOR: Clinical voice disorders utilize jitter, shimmer, and harmonics-to-noise ratio (HNR) to discriminate pathological from healthy voices in laryngology. Prosodic range reduction and monotony associate with psychiatric stress in multiple cohort studies. Fundamental pitch variability, speech rate, pause patterns, and voice quality change under cognitive load and acute stress in controlled paradigms.
Critique / Null AGAINST: Acoustic features are multicausal, heavily influenced by hydration, microphone, room acoustics, native language, sleep, caffeine, and training. Attributing them to a stable "subconscious state" without a mechanistic model is overreach. Many speech psychopathology machine learning classifiers overfit on small datasets and fail to replicate on new cohorts. No stable "consciousness fingerprint" is medically accepted.
Replication: Strong in vocal pathology; mixed in speech-based psychopathology classifiers; weak or absent for universal subconscious profiling from short voice clips without a baseline.
Ashta uses modern acoustic analysis engines and large language models (LLMs) to capture and evaluate these acoustic markers from brief voice recordings, tracking variables like hesitation and cognitive-load. We measure these signatures before and after sessions to identify changes. We do not make clinical diagnoses, systemic diagnostic claims, or medical assertions. Voice analytics are used strictly as a research biomarker to correlate acoustic variations with stress-resilience and wellness outcomes.
establishedHeart Rate Variability (HRV)
Heart Rate Variability (HRV) is a primary physiological marker of autonomic nervous system function, reflecting the balance between the sympathetic (fight-or-flight) and parasympathetic (rest-and-digest) pathways. The variation in time intervals between consecutive heartbeats is heavily modulated by vagal tone—often described as the "vagal brake"—which slows the heart rate and supports recovery from stress.
Evidence FOR: RMSSD and vagal-band HRV (HF-HRV) index parasympathetic cardiac modulation; low HRV associates with stress, inflammation markers, and cardiovascular risk in large epidemiology and cohort studies. Paced breathing at approximately 6 breaths/minute (optimal respiration rate), exercise, CBT, and biofeedback show moderate increases in HRV and parallel stress reductions in randomized controlled trials.
Critique / Null AGAINST: Readings are heavily altered by systemic confounds such as sleep, alcohol, caffeine, illness, hydration, cycle phases, medications (like beta-blockers), movement artifacts, and breathing rate, without indicating deep psychological states. Time-domain and spectral-domain measures are poorly standardized. Commercial wearables often misreport vagal-band values compared to research-grade ECG. Not a direct meter of consciousness.
Replication: Highly robust in population studies for cardiovascular risk; moderate for stress-reduction interventions; weak for parapsychological claims of telepathy or remote healing.
Within the Ashta protocol, HRV is measured primarily through the phone itself — no wearable required. Two camera-based methods make it universally accessible: contact photoplethysmography (PPG), where a fingertip held over the camera lens and light registers the pulse waveform; and contactless remote PPG (rPPG), where the camera reads the subtle pulse-driven colour changes in facial skin — minute fluctuations in the red channel — to estimate beat-to-beat intervals. Because the phone is already in nearly everyone's pocket, camera-based HRV is the most scalable instrument in the panel. Optional wearables (chest straps, rings, bands) can be layered in for participants who have them, adding a higher-fidelity reference — and the accuracy gap between phone-camera HRV and wearable-grade HRV is itself one of the methodological questions Ashta tests. We track HRV at rest and during active sessions to determine whether self-development work correlates with objective shifts in stress regulation and autonomic stability, rather than relying solely on self-reported psychological states.
under testInstrumented kinesiology
Instrumented kinesiology, or somatic force-response testing, is positioned strictly within our "under-test" register. Mainstream medical and scientific consensus classifies applied kinesiology as unproven, with published research showing a lack of diagnostic validity. The primary empirical anchor for this null result is a double-blind study by Schwartz et al. (2014), which tested the validity of applied kinesiology under rigorous conditions (PMID 24607076). In this trial, kinesiologists and a hand dynamometer produced a hit rate of only 53% (p = 0.258, non-significant), and pressure sensor data showed no force difference in the predicted direction. Consequently, kinesiologists were unable to identify supplement status in sealed bottles, indicating that the technique does not provide a reliable diagnostic tool upon which health decisions can be based. Positive claims are explained by suggestion, expectancy, and tester pressure (the ideomotor effect).
Evidence FOR: Mainstream sports science validates mechanical force measurement via dynamometry. Subjective alternative medicine claims rest on anecdotes.
Critique / Null AGAINST: Applied kinesiology fails to demonstrate diagnostic validity under blinded conditions. Schwartz et al. (2014) showed a null result. Suggestion, expectancy, and tester pressure explain outcomes; double-blind designs collapse effects.
Replication: Negative replication is dominant. Prior blinded studies align with Schwartz 2014. Somatic response claims collapse under strict blinding.
To eliminate the well-documented ideomotor effect—where unconscious expectation drives muscle response—Ashta uses a double-blind, app-mediated measurement protocol. This protocol utilises an externally-developed mobile instrument that captures a digitised force-response, replacing the subjective hand-pressure of classic muscle testing with an objective, logged measurement.
Our experimental design tests several variables not addressed in previous null studies:
- Independent Moderator Stratification: Testing whether somatic response accuracy correlates with a participant's independently measured developmental level, a hypothesis originating from the Map of Consciousness framework in David Hawkins' Power vs Force.
- Dual-Response Divergence Analysis: Participants register a conscious guess of a hidden target prior to somatic testing. We then analyse whether somatic responses that diverge from conscious expectations yield a signal above chance, which controls for the ideomotor effect of conscious belief.
- Scale: Expanding the cohort from small physical groups to a large-scale, pre-registered app-mediated study to identify potential conditional effects.
under testFocused intention on physical systems
Ashta tests focused intention on physical systems as part of its experimental register, investigating whether collective intention can measurably influence external matter or systems. This hypothesis builds on the lineage of Lynne McTaggart's "Power of Eight" groups and the Princeton Engineering Anomalies Research (PEAR) studies. In mainstream physics, the prior probability of such an effect is considered extremely low, as there is no known physical mechanism for mind-on-matter interaction, and independent replications of similar studies have yielded null or disputed results.
Evidence FOR: PEAR laboratory reports claim small mean shifts in random event generators (REG) correlated with operator intention. The Global Consciousness Project reports deviations around major world events. Schwartz (2019) published a sensory study on taste preference (PMID 30279068).
Critique / Null AGAINST: Mean shifts are tiny and often at the edge of statistical detection; publication bias and optional stopping inflate significance. Independent replications of micro-psychokinesis show null results when pre-registered, powered, and shielded. The Schwartz (2019) wine study was subject to potential confounds (aeration, temperature differences, handling asymmetries, and server bias).
Replication: Contested and inconsistent. Mainstream physics rejects mechanism. Replications by independent laboratories are dominant nulls.
To evaluate this phenomenon, Ashta employs two primary protocols:
- Random Event Generator (REG) Deviations: Testing whether focused group intention can deviate certified hardware random number generators (RNGs) from chance, using pre-registered stopping rules and blinded trials to control for selective reporting.
- Sensory-Readout Intention Protocols (Blind Wine-Tasting): Replicating and refining a sensory protocol published by Schwartz (2019), which reported that tasters preferred wine treated with focused intention (PMID 30279068). To resolve potential confounds in the original study—such as aeration, temperature differences, handling asymmetries, and server bias—Ashta enforces double-blind pouring, identical transport journeys for treated and control carafes, and triangle sensory detection tests.
For trials involving mineral elements, such as cobalt-doped hydrothermal quartz, the crystal is treated solely as a ritual focusing object. Ashta maintains a strict scientific firewall: crystals are never presented as active agents or energy sources, and they are always controlled against equal-mass glass shams. In alignment with mainstream physics and physical information limits, Ashta rejects explanations based on non-local shortcuts or somatic resonance theories for telepathy or mind-on-matter effects, staying agnostic on mechanism and committed to reporting null results.
under testTelephone telepathy
Telephone telepathy is the contested hypothesis that a person can know who is contacting them at a rate higher than chance. Ashta tests it as a forced-choice guessing game in the Spanda app: out of a friend group, one member is randomly designated each round and you guess who, with the chance baseline at exactly 1-in-N — the larger the group, the sharper the test. It is an open hypothesis under test, run at large-N under pre-registered, blinded conditions, with every result published including nulls. Read the full telephone-telepathy & Spanda-app protocol →
Evidence FOR: Rupert Sheldrake's experiments propose that individuals can anticipate caller identity at rates higher than the 25% chance expectation.
Critique / Null AGAINST: Mainstream science holds that telepathy is unproven and lacks a physical mechanism. Potential sensory leakage pathways include ringtone cadence, call delays, caller ID metadata, time-of-day habits, and assistant knowledge. Replications under strict blinding (Faraday pouch, automated call routing) tend toward chance.
Replication: Internal positive series vs inconsistent/null external independent replications under strict blinding.
expandingExpanding biomarker panel
Ashta maintains an open, expanding panel of objective biomarkers to build a comprehensive view of individual well-being over time. This envelope integrates commercial wearable rings and bands to capture longitudinal sleep quality, autonomic recovery, and daily stress metrics. For advanced cohorts, Ashta utilises third-party electroencephalogram (EEG) and Heart Rate Variability coherence tools to monitor cortical activity and physiological alignment during meditative practices. By expanding the biometric envelope, Ashta avoids relying on any single physiological indicator, assessing whether changes in psychological states correlate with broader systemic health signatures.
