Ideas behind
the tools.

Miller's 1956 paper offered a rough estimate of about seven chunks in certain short-term memory tasks, not a universal limit on priorities. Cowan's later review distinguishes that estimate from an average capacity of about four chunks under specified conditions. Task demands, rehearsal, and grouping information into chunks matter.

7 Buckets uses seven as a practical organising framework. Its cap encourages you to choose what matters now; it does not measure your working-memory capacity or establish that performance collapses at an eighth priority.

Dijksterhuis, Bos, Nordgren, and van Baaren's 2006 study reported benefits from distraction in some complex consumer choices. It examined deliberation without attention, not overnight sleep or a REM-sleep mechanism.

Nieuwenstein and colleagues' 2015 meta-analysis and large replication found no reliable support for a general advantage of distraction over conscious deliberation.

Decision Tiebreaker is a reflection aid: record your reasons, pause if time allows, and review them later. Sleeping on a decision is optional, not a proven route to a better answer. Check the facts and consequences rather than treating a morning feeling as proof.

McKinsey's explanation describes a strategic framework for attending to current business, emerging opportunities, and future ideas at the same time. It draws on The Alchemy of Growth by Baghai, Coley, and White.

Horizon 1 concerns the core business; Horizon 2 concerns emerging opportunities; Horizon 3 concerns exploratory ideas. Projects can move between horizons as they develop.

Goal Map and Horizon Score adapt this business framework for personal planning. Their time ranges are tool conventions, not rules from the original model. The source does not establish a growth multiplier, an optimal allocation, or the same outcomes for individuals.

Zaccaro and colleagues reviewed studies of slow breathing in healthy participants. They reported links with changes in heart-rate variability and psychological outcomes such as relaxation and reduced arousal, while noting that the underlying mechanisms remain under debate.

The studies used different techniques and protocols. Their findings do not establish that this app's box-breathing pattern reduces cortisol or reliably changes your physiological state within a two-minute session.

Two-Minute Reset offers paced breathing as a wellbeing exercise. Responses vary. Keep your breathing comfortable and stop if you feel dizzy or unwell.

Gollwitzer distinguishes a goal intention from a plan specifying the situation in which to act: when, where, and how. These plans can connect an intended action with a concrete cue.

Research suggests implementation intentions can help people follow through, with outcomes depending on the task and context. It does not justify a universal multiplier for every goal.

Weekly Reset is designed to help turn broad intentions into specific plans. That design is an application of the idea, not evidence that this tool has been scientifically validated.

Sweller's research examines how demands during problem solving affect learning. Working-memory constraints help explain why the way information is presented and tasks are structured can matter.

Applying these ideas to a personal energy audit is a practical adaptation, not a measure of a single mental fuel tank. Different activities and contexts make different demands on attention.

Energy Audit is intended to help you reflect on where your time and attention go. This research does not validate the tool's scores or establish a daily capacity for creative work.

Baumeister and colleagues' early experiments proposed that prior self-control demands could affect performance on a later task. This does not establish that every choice consumes a fixed daily resource or that later decisions are always worse.

The Constraint Filter is intended to help define personal rules for recurring choices. Such rules may simplify a decision, but the cited paper does not prove that they are the only defence against fatigue or more effective than every alternative.

Amabile and Kramer's workplace diary research linked progress on meaningful work with positive emotions and motivation. Their findings concern the workplaces studied, not a universal ranking of every source of motivation.

Momentum Log is intended to make small steps visible. A record can help you reflect on progress and setbacks, but the study did not test this app or guarantee that logging progress improves performance.

Zeigarnik studied memory for interrupted and completed activities. Remembering an unfinished task is not evidence that every open task continuously consumes a measurable amount of mental energy.

Mind Sweep is intended to give you a place to record outstanding tasks and review them later. Writing a list may help you organise concerns, but it does not complete the tasks or guarantee that they stop coming to mind.
