Q: Can we measure consciousness using science?
Krishna: People say: Because consciousness is a subjective experience that can't be explained by objective data alone, it cannot be measured accurately. Moreover, by mixing it with spirituality , they say consciousness is infinite and can't be measured.
Consciousness, at its simplest, is awareness of internal and external existence. However, its nature has led to millennia of analyses, explanations, and debate by philosophers, scientists, and theologists. Opinions differ about what exactly needs to be studied or even considered consciousness.
Various people produce various definitions for consciousness and say it isn't just neural activity that Produces consciousness!
According to science, consciousness is defined as a state of awareness of one's surroundings, thoughts, and sensations, essentially the subjective experience of being and perceiving the world, which is believed to arise from complex neural activity within the brain, particularly involving integrated information processing across different brain regions; it's often characterized by the ability to self-reflect and be aware of one's own mental states.
“Consciousness" is the function of the human mind that receives and processes information, crystallizes it and then stores it or rejects it with the help of the following:
1. The five senses
2. The reasoning ability of the mind
3. Imagination and emotion
4. Memory
The five senses enable the mind to receive information, then imagination and emotion process it, reason judges it, and memory stores or rejects it.
The exact parts of the human brain where those functions take place are supposedly defined by neurophysiology . An important observation is that the more information one is able to gather and process, the more “aware" and the more “conscious" one becomes regarding one’s internal and external world . Awareness and wakefulness represent the two main components of consciousness. Awareness is defined by the content of consciousness, and arousal is defined by the level of consciousness. Awareness contains self-awareness, which perceives the internal world of thoughts, reflection, imagination, emotions, and daydreaming, as well as external awareness, which perceives the outside world with the help of the five senses. From a neurological point of view, consciousness comprises a spectrum of states that range from physiological states to states of impaired consciousness that are monitored by specific criteria included in the Glasgow Coma Scale but also comprises modified states either by self-training (transcendental meditation) or by drug intake. (3)
Neuroanatomical studies revealed numerous structures implicated in the consciousness that were very well described by scientists. (4)
However, levels of consciousness can be measured scientifically using a variety of methods, including brain waves, behavioural measures, and artificial intelligence.
Scientists studying consciousness are attempting to identify correlations between measurements of consciousness and the physical world. Consciousness can only be measured through first-person reports, which raises problems about the accuracy of first-person reports, the possibility of non-reportable consciousness and the causal closure of the physical world. Many of these issues could be resolved by assuming that consciousness is entirely physical or functional. However, this would sacrifice the theory-neutrality that is a key attraction of a correlates-based approach to the study of consciousness (1)
How can we measure whether and to what extent a particular sensory, motor or cognitive event is consciously experienced? Such measurements provide the essential data on which the current and future science of consciousness depends, yet there is little consensus on how they should be made. The problem of measuring consciousness differs from the problem of identifying unconscious processing. For instance, in subliminal perception experiments it is desirable to know whether or not a stimulus has been consciously perceived, and in implicit learning paradigms it is interesting to know whether the relationships between different consciously represented stimuli are unconsciously inferred. Measuring consciousness, however, requires saying something about conscious level (Glossary) and conscious content beyond the zero-point of unconsciousness. (2)

If you check out Standard Psychology there might be a way to measure the results of it. There's something called the Intelligence Interval which basically measures an individual’s interpretation of the meaningful experiences in their own life. It's the closest thing to standardizing, defining and measuring “consciousness” to date.

Tononi’s Integrated Information Theory is designed to measure the differing levels of the quality and quantity of consciousness by using a mathematical based phi method. ITT also deals with classifying the ability of each level of consciousness to differentiate between uncertainties.

Before we measure it, let’s see if we can arrive at a consensus on what consciousness is. Consciousness is a cognitive function; it consists in the act of paying attention to signals. Attention consists of a current of electrical impulses generated in the brain stem, connected to the other brain regions / structures where those signals, also electrical impulses, are processed. All experience, thoughts, emotions, sensations, memories, and attention itself, consists of electrical impulses conducted by chemicals in and between brain cells. Altering one’s consciousness naturally like sleep, or artificially with mind-altering chemicals that amplify and distort perceptions has led us to imagine that consciousness is something magical and mystical when in reality, it is an evolved survival mechanism / strategy that all animals must have to survive. An unconscious animal cannot eat, reproduce or avoid a predator. Only animals have consciousness because only animals need to be conscious to continue to exist.
