'''Psychoengineering''' is a research-based [[engineering]] practice designed to control and mitigate mental disorders such as depression and anxiety. This site serves as a guide to psychoengineering and how to perform it.
 
Humans have two primary systems of acquiring knowledge: [[w:Intuition|intuition]], a fast and unconscious reflex; and [[w:Logical reasoning|logic]], a slow and deliberate process.<ref>{{harvnbsfn|Kahneman|2011|pp=20-23}}</ref> Each of these dual cognitive methods is designed to interface with a specific type of information,<ref>{{harvnbsfn|Darlow|Sloman|2010|pp=1-3}}</ref> and are thus connected to different parts of the brain. The neural circuitry of intuition (the amygdala, basal ganglia and lateral temporal cortex)<ref>{{harvnbsfn|Lieberman|2003|p=7}}</ref> is linked to circuitry related to working memory, motor control, attention, perception, and empathy.<ref>{{harvnbsfn|Ramezanpour|Fallah|2022}}</ref><ref>{{harvnbsfn|Roozendaal|et al.|2009}}</ref><ref>{{harvnbsfn|Schacter|et al.|2020}}</ref> Meanwhile, the neural circuitry of reason (anterior cingulate cortex, prefrontal cortex, and the medial temporal lobe including the hippocampus)<ref>{{harvnbsfn|Lieberman|2003|p=10}}</ref> is linked to circuitry related to long-term memory recall, executive function, and complex decision-making.<ref>{{harvnbsfn|Aharoni|et al.|2013}}</ref><ref>{{harvnbsfn|Friedman|Robbins|2021}}</ref>
 
These systems are implicated in different behaviors, but like everything in the brain they are deeply connected and regularly interface with each other. For example, one could notice a dessert table and be drawn to it by their intuitive, perceptual mind - but ultimately be drawn away from it by their logical mind.<ref>{{harvnbsfn|Darlow|Sloman|2010|p=1}}</ref>{{efn|Psychoengineering uses "intuitive/logical mind" for these systems, but they have many different names in contemporary psychology. Stanovich uses "systems 1/2", so as to not give a preference to either system. Evans has used "old/new mind", in reference to the evolutionaryphylogenetic age of each system.<ref>{{harvnbsfn|Evans|Stanovich|2013|p=1}}</ref> Darlow and Sloman use "intuitive/deliberate system" to emphasize the level of conscious control present in each.<ref>{{harvnbsfn|Darlow|Sloman|2010|p=2}}</ref>}}

This [[dialectic of mind|dialectic]] was first hypothesized by [[dialectic of mind#history|ancient philosophers]], who developed practices to synthesize the two minds. These practices, refined by neuropsychology, form the basis of the techniques used in [[w:dialectical behavioral therapy|dialectical behavioral therapy (DBT)]]<ref>.{{harvnbsfn|Linehan|Dimeff|2001|p=1}}</ref>. The goal is to achieve the [[synthetic mind]]:

Within the synthetic mind, the objective is to [[debug]] and eliminate unwanted behaviors. [[Bugs]] typically have a fundamental [[cognitive distortion]] that fuels them.

All of these components of well-being should be improved simultaneously, but it is important to note that elements at the base are typically more capable of overwhelming the synthetic mind.
 
'''[[Neurochemistry]]''': Chemistry of individual neurons, determined genetically, which can significantly alter [[hedonic baseline]]. [[w:Monoaminergic|Monoaminergic]], [[w:GABAergic|GABAergic]], and [[w:glutamatergic|glutamatergic]] systems are strongly implicated in depression{{sfn|Kaltenboeck|Harmer|2018|p=1}} and anxiety.{{sfn|Martin|Ressler|Binder|Nemeroff|2009|pp=1-3}} Treatment: [[w:psychopharmaceutical|psychopharmeceuticals]].
 
'''[[Somatic state]]''': Conditions like sleep deprivation<ref>{{harvnb|Harrison|Horne|2000}}</ref> and body temperature{{sfn|Doohan|Watzek|King|White|Stewart|2023}} can negatively affect logical decision making. Masicampo and Baumeister observed that drinking lemonade mixed with sugar as opposed to [[w:Splenda|Splenda]] after an energy-depleting self-control task increased rule-based decision making.{{sfn|Masicampo|Baumeister|2008}}{{sfn|Gailliot|Baumeister|DeWall|Maner|Plant|Tice|Brewer|Schmeichel|2007}} Exercise has also been shown to improve problem-solving abilities.{{sfn|Hillman|Erickson|Kramer|2000}} Treatment: [[somatic management]].
 
'''[[Emotional state]]''': Distress has a significant effect on logical reasoning - arachnophobes perform significantly worse than non-arachnophobes on logical tests that relate to spiders, for example.{{sfn|Jung|Wranke|Hamburger|Knauff|2014}} Loneliness{{sfn|Şimşek|Koçak|Younis|2021}} and anger{{sfn|Zajenkowski|Zajenkowska|2015}} also negatively correlate to logical ability. Treatment: [[acceptance therapy]].
 
'''[[Perspective]]''': Perspective shifts such as [[w:distancing (psychology)|self-distancing]] and the [[w:growth mindset|growth mindset]] have a neurological basis in provoking self-reflection and heightening intrinsic motivation, respectively.{{sfn|White|Kross|Duckworth|2015}}{{sfn|Ng|2018}} Treatment: [[cognitive defusion]].
