Research and sources.

This is where Protected Hour started.

As I paused my jewellery making business while we put our home up for sale, I needed to make sense of the changes about to happen. Did I continue with the launch of my jewellery brand, or wait until after the house sale, or drop the idea completely?

As the saying goes, ‘life happens’.

I journalled through the options and realised that the answer lay in the more than 60 personal development books I had already read.

The notes and research below quickly became the basis for Protected Hour.

Sources are numbered in the order they first appear in the book, so the same number may show up in several chapters.

I am hugely grateful for the time and energy these amazing authors and academics have put into their work. I want to acknowledge their contribution to Protected Hour.

This principle applies broadly: 80% of results typically come from 20% of efforts. Related to this is Price’s Law, formulated by Derek J. de Solla Price in ‘Little Science, Big Science’ (1963), which states that the square root of the total number of
    contributors in a field produce half the output: an even more concentrated distribution (e.g., in a group of 100, just 10
    produce 50% of results). See Richard Koch, The 80/20
    Principle (Crown imprint, 1998) for accessible modern

    development. New York: Holt, Rinehart and Winston.

    In this landmark study, teachers were told certain students would show ‘unusual intellectual gains’ based on a test for ‘intellectual blooming’, when these children were actually randomly selected. By year’s end, these students showed genuine IQ gains and improved academic performance.

    The teachers’ positive expectations changed their interactions: more encouragement, patience, and higher standards. As the authors concluded, ‘When teachers expected certain children would show greater intellectual development, those children did show greater intellectual development.’

    The reverse is equally powerful. Babad, E.Y., Inbar, J., & Rosenthal, R. (1982) [‘Pygmalion, Galatea, and the Golem: Investigations of biased and unbiased teachers’, Journal of Educational Psychology, 74(4), 469-474] distinguished the Golem Effect: teachers holding negative expectations displayed more critical and unfriendly behaviour, and their students performed measurably worse, even when controlling for actual ability.

  2. Festinger, L. (1957). A theory of cognitive dissonance. Stanford University Press, Stanford, CA.

    Cognitive dissonance theory posits that individuals are motivated to maintain consistency amongst their cognitions (beliefs, attitudes, values, and behaviours). When contradictory cognitions are held simultaneously, the resulting psychological discomfort, an aversive mental state, motivates the individual to reduce the inconsistency. Festinger proposed three primary methods for reducing dissonance: (1) changing behaviour to align with beliefs, (2) changing beliefs to justify behaviour, or (3) adding new cognitions that reconcile the inconsistency. The theory demonstrates that this tension between conflicting cognitions creates measurable psychological stress that impacts decision-making, performance, and behaviour.

  1. Hernán Cortés and the scuttling of ships upon landing in Mexico (1519). Contemporary source: Bernal Díaz
    del Castillo, The True History of the Conquest of New Spain (written 1568, published 1632). Díaz, an eyewitness and
    soldier in Cortés’s expedition, explicitly refers to ‘destroying our ships’ rather than burning them. Later passages confirm ships were dismantled/scuttled, as materials including iron, chains, and bolts were salvaged for subsequent use. The
    popular motivational phrase ‘burning boats’ is a modern
    simplification; historical evidence indicates deliberate scuttling (sinking/disabling) to prevent retreat and ensure total

  8. The Reticular Activating System (RAS)
    Throughout this book I refer to the RAS as shorthand to
    explain a very complex and incredible system within your brain. My aim for this book has always been to give you a solid and reliable method to achieve your aims and goals, backed by a strong body of science and practical experience from both myself and other reputable authors in this arena.

    I am aware that in the book I have simplified the inner workings of the mind to a soundbite, so I want to use this section to give you a more rounded explanation of what is happening with your RAS and mind.

    How Signals Enter the System

    The RAS sits in your brainstem, quietly receiving a constant stream of information from your senses. Signals come in from your eyes (visual system), ears (auditory system), balance
    organs in your inner ear (vestibular system, one of the most potent inputs), and your entire body’s sensory network: touch, pain, temperature, pressure, even your sense of body position (proprioception).

    These signals arrive through ascending tracts from the spinal cord and cranial nerves.

    Why Smell is Different
    Interestingly, smell is the exception: it bypasses the RAS and thalamus entirely, going directly from the olfactory bulb to areas like the piriform cortex, amygdala, and hippocampus (regions involved in emotion and memory). This unique direct pathway to limbic structures may explain why odours powerfully evoke emotions and memories, and why smell plays crucial roles in detecting threats (like spoiled food or smoke), social recognition, and mate selection.

    The Thalamus: Your Brain’s Gatekeeper
    From the RAS, these filtered signals travel primarily to the thalamus, the brain’s central relay station. But the thalamus isn’t just a passive messenger. It actively decides which information is important enough to reach your conscious awareness in the cerebral cortex, and which can be safely ignored. The thalamus, working with auditory cortex and frontal-parietal attention networks, is where the ‘cocktail party effect’ originates: your brain’s ability to filter background noise and detect personally significant information.

    The Prefrontal Cortex Connection
    Signals sent to the prefrontal cortex support goal-directed behaviour, planning, and decision-making. Critically, this is a two-way communication pathway. While the RAS and thalamus send filtered information up to the prefrontal cortex, the prefrontal cortex sends signals back down, a process called top-down modulation.

    Research shows that when you consciously set goals or focus attention, the prefrontal cortex sends ‘bias signals’ throughout the brain, including back to the thalamus and sensory processing areas. These signals essentially reprogram the filtering criteria, telling the thalamus and RAS what to prioritise based on your current goals and intentions.

    This top-down modulation from the prefrontal cortex can enhance processing of goal-relevant stimuli, suppress processing of goal-irrelevant information, and modify what the thalamus allows through to conscious awareness.

    In neuroimaging studies, when participants are given specific goals or focus instructions, researchers can observe increased activity in the prefrontal cortex followed by changes in how sensory information is processed in other brain regions, demonstrating this top-down influence in action. The prefrontal cortex literally changes what your brain pays attention to based on what you’ve consciously decided matters.

    This bidirectional communication (sensory filtering going up, goal-based modulation coming down) forms a feedback loop that allows conscious intention to shape unconscious filtering.

    The RAS also communicates with other critical brain regions: the basal forebrain (which helps maintain wakefulness and attention), the hypothalamus (controlling sleep-wake cycles, hunger, body temperature), and through the thalamus, connects to the hippocampus (forming and storing memories) and the limbic system (processing emotions).
