Introduction

No matter the Earth is flat or spiky, globalization has passed the point of no return. In a fast-changing globalized world, increasing movements and exchanges between different regions, cultures, and populations worldwide are undeniable. Such movements and exchanges result in acculturation processes all over the world.

The mindsponge mechanism is proposed by Vuong Quan Hoang & Nancy K. Napier ^[1][2] for explaining how and why an individual "learns and unlearns" cultural values, which helps us better understand the complexity of acculturation in a global context. Originally, the framework was used to study acculturation phenomena and the development of global mindset at individual and organizational levels by answering the question: “What is the determining mechanism of absorbing and ejecting cultural core values in a mindset?”. More specifically, it demonstrates a global mindset as a dynamic process of inducting and expelling socio-cultural values. Through this process, executives, managers, and corporations could replace inappropriate values with new values that help them adapt to multicultural and global settings ^[3], eventually improving their happiness at work ^[4].

Recently, the mindsponge mechanism has been developed into mindsponge theory based on various evidence from natural sciences ^[5].

Main components

The conceptual diagram of the mindsponge framework consists of five components: 1) mindset, 2) comfort zone, 3) multi-filtering system, 4) cultural and ideological setting, and 5) cultural values (see Figure 1). Such components and their connections are constructed by referring to prior prominent theories and models: self-affirmation theory, 3D multi-filtering process, information processing model, inductive attitude, and model of acculturation.

The framework is constructed assuming that every person has a mindset, which is a non-empty set of core cultural values or beliefs that are central to individual identity ^[65]. The mindset is demonstrated by the red nucleus located in the middle of the diagram. An individual uses the core values as benchmarks explicitly and implicitly, especially when they need judgment on the usefulness and appropriateness of emerging cultural values (or information) and when they need to make decisions and responses. This function of the mindset gives the individual a self-protection mechanism of their “self”, which is analogous to the self-affirmation theory. However, the core values can still be changed by attacks of emerging values and clashes with other core values

The mindset is surrounded by a light blue circle, which is called the comfort zone. Values that are close and supportive to the mindset are constituting this zone. The Comfort zone is a buffer playing two functions. First, the comfort zone protects the mindset from external shocks – for instance, cultural shocks. Second, the comfort zone helps filter and evaluate information regarding the appropriateness and usefulness of any emerging value.

When information or cultural values enter the comfort zone from the environment, they also enter the multi-filtering system. The 3D multiple filters inductive attitude and trust evaluators are two fundamental parts of the system. The 3D multiple filters play two roles: 1) integration and 2) differentiation. While integration synthesizes and incorporates information and value that are compatible with the core values, differentiation measures the difference between the emerging and existing values to assess the cost and benefit of accepting or rejecting the emerging values (or even replacing old core values with the new ones). The closer the new values get to the mindset, the more stringent evaluation they receive.

The blue arrows represent the inflow of the entering information or values, whereas the orange arrows indicate the outflow of inappropriate information or values. Both flows are driven by the 3D multi-filtering process ^[76] and the inductive attitude ^[87]. Inductive attitude and the 3D multi-filter process facilitate trust-building exercises for comfort zone values. By reaching the critical mass, the emerging value is allowed to enter the core mindset by the trust evaluator. In reverse, a core value can lose its trust level then the evaluator forces it out of the nucleus. The trust evaluator, which can be understood as the cost-benefit judgment of the individual, plays the guarding role during the whole filtering process, at any place and any time.

Based on the information processing mechanism of the mindsponge, there can be two extremes. The first case is when an individual completely ignores the emerging values from the surrounding environment. This is because the 3D multi-filtering process does not work, and the individual’s “radar” is not turned on, making the individual not receptive to the information from the environment. Another reason lies in the cost of absorbing new values or information. In other words, the individual perceives incorporating new values or information into the mind to be too expensive, so the existing set of values is kept unchanged. The second extreme case is when the individual is so eager to change that they can easily replace their existing core values or beliefs with the new ones. This situation is attributable to the negligent trust evaluators, making the individual perceive the cost to change relatively low.

A simplified mindsponge information process

The flow of information in a simplified mindsponge process comprises of the following steps.

Step 1: Information from the external environment or internal memory enters the buffer zone. Here the information is evaluated by the filtering system.

Step 2: The information’s value is subjectively judged based on its perceived costs and benefits. If the perceived benefit is greater than its perceived costs, then the information’s value is deemed positive, and vice versa. Trusted values from the mindset (stored in memory and retrieved when needed) are used as references for the judgments (related trusted values are connected and compared to the currently evaluated information).

Acceptance: The information is accepted if the information’s value is positive.

Rejection: The information is rejected if the information’s value is negative.

Step 3: If the information is accepted, it can move into the mindset and become a new trusted value. This new trusted value can be used as a reference for future evaluations of information related to it. If the accepted information directly corresponds to a behavior (whether mental or physical), that behavior will be carried out.

Main characteristics

Information generating

Processing information also means new information is generated. In the evaluating processes, the evaluated information interacts with other information used as references and changes its value. Since the subjective values of information are created from connecting and comparing them with other trusted values, any thinking activity causes the processed values to become different (to some degree) from their original input value. The mindsponge process employs the principles of induction and innovation, like the serendipity process ^[98]. It can also be said that information processing is itself information generating, with its properties and function deeply intertwined. Even remembering past events (a simple, quick re-evaluation of trusted perceived ‘facts’) can cause changes in the recalled information’s content and attitude toward it over time. The information-generating aspect can also be observed on a collective level; for example, when new cultural values are added, adopted, and mixed with the existing cultural values of a community, new and unique local values can be created within that community.

Trust: the ‘priority pass’

In the Mindsponge framework, trust toward a set or source of information (a group of information sharing some similar properties) is the belief about its reliability or generalized value. Trust is often applied to a source of information, such as a family member, intimate partner, or a person of authority (e.g. governmental agent) or expertise (e.g. scientist). It can also be applied to an information set (e.g. ideology, doctrine, group identity).

Trust acts as a ‘priority pass’ that quickens the evaluation process. The trust value is either negative (distrusted) or positive (trusted); if the value is neutral, it can be said that there is no existing trust value (indifferent). The trust value is also put on a gradient of belief strength (degree of trust). A positive trust value helps shift the perceived value of related information to be more beneficial and vice versa. For example, if a daughter trusts her father, she will find it easier to accept information from him than from a neutral stranger. However, if she distrusts him, the effect will be the opposite. On a collective level, generalized trust (trusting other people in the society) closely goes with social connectedness ^[109]. The ‘priority pass’ effect of social connectedness was shown to influence the receptibility of specific information groups ^[10][11][12]. Trust can be considered a special type of trusted value from the mindset which is used as a group reference in the cost-benefit judgment.

Since utilizing trusts (attaching a general added value to a group of information), the mind can save more energy and time than evaluating new information from scratch. The information needs to be previously accepted and integrated into the mindset before it can function as a priority pass. In other words, before trusting a certain source, the value of ‘this source is reliable’ must first be evaluated and become trusted (the process of trust-building). The opposite direction is distrust-building. Once a general perceived value of the group has been developed, the other information belonging to that same group is expected to have a similar value.

Updating

The mindset is always changing because the Mindsponge processes do not stop as long as the mind still functions normally. Accepting beneficial new information and rejecting waning old information cause changes in the mindset’s content. The set of trusted values need to change for the mind to adapt to its constantly changing living environment. Because the mindset determines the operation of the filtering system, changes in mindset also lead to changes in the evaluation of new information. A mutually interacting circular cause-effect relationship between the mindset and the filtering system updates the whole mindsponge apparatus. This updating manner can normally be observed in our daily life (individual level) and throughout human history (collective level). For example, a person who hated broccoli as a child turns to enjoy it when they grow older; a former society with widespread racial discrimination turns into a modern society that respects and embraces racial equity, etc.

Belief reinforcement is an important aspect of the Mindsponge updating manner. A value accepted into the mindset will be used as a reference for subsequent evaluations of related information, thus increases the similar information’s perceived value and make acceptance easier (and vice versa for information-carrying opposite values). The subsequent acceptance or rejection reinforces the trusted value in its respective direction. For example, a person who believes that lions are vicious creatures will find it easy to believe the news about a recent lion attack. This new information also reinforces that person’s negative view of lions. By contrast, that person finds it hard to believe information about docile lions. If the information carries a value opposite to the trusted ones with enough impact, it may be accepted instead, and the direction of belief will be shifted; for example: hypothetically, somehow lions were genetically modified to become gentle vegetarians, people would gradually start to believe that they are not dangerous.

Applications

As a conceptual framework for information processing, the mindsponge concept has been applied in various fields of social sciences. It is often used for studying and explaining the cultivation process of a global mindset, innovation, and creativity ^{[12][13][14][15]}. Specifically, the framework was used to design the i2Metrix survey, which measures Vietnamese leading businesses’ inclusive corporate innovation capacity through ten dimensions ^[1615]. Among those dimensions, the Mindsponge dimension focuses specifically on the ability to absorb and integrate emerging cultural values into the corporate mindset for innovative change and creative performance. Due to the ability to demonstrate the dynamic process of new-value absorption and inappropriate-value replacement at the individual level, the mindsponge concept is recommended as a promising tool to explore whether the interaction between expatriates’ personality and experience of cultural differences could influence creativity ^[1716]. Outcomes of the mindsponge processes are also found to be the determinants of entrepreneurs' decisions to start a business ^[1817]. The mechanism is also used to explain how Covid-19 vaccines have been produced within a limited time ^[19]. 

The mindsponge framework could explain many socio-cultural issues. Besides the acculturation process ^[2018][2119], it is also used in conjunction with the concept of cultural additivity in examining the acceptance and rejection of religious values in spiritual healing ^[2220]. The study shows that cultural additivity and the mindsponge mechanism allow the additions of new and contradicting values, which makes the adaptation to spiritual practices and the reception of different traditions and values more applicable. Based on the mechanism of Mindsponge, Ärleskog et al. suggested that building a structured reflection model to raise awareness constantly might change the healthcare users’ perspective, which consequently helps improve the co-production practices ^[2321].

The complexity and dynamic of mindsponge are also useful in studying mental health and psychological issues, like how depressive disorders are attributable to acculturative stress ^{[2422][2523][2624]}. More specifically, individuals living in a new environment with different cultural settings need to adapt and establish their social networks. Making new friends in a new cultural environment is equivalent to accepting new cultural values, so the filtering process will be performed to evaluate whether to trust the new friends/values or not. During this process, if the individual trusts the new friends/values, they will let the friends/values come closer to themselves/mindset. In contrast, if conflicts happen between the new friends/values and the individuals/mindsets, the individual’s filter will push the new values away from the mindset, creating a larger emotional distance between the individual/mindset and the new friends/values. Such distance might result in loneliness which is one of the primary predictors of depression.

The mindsponge framework was recently expanded to be the theoretical foundation for investigating how the mind processes suicide-related information ^[1110]. The psychological mechanism of the formation or cessation of suicidal thoughts focuses on two principles in the framework: information accessibility (the availability of information sources and the subjective perception about them) and information filtering (with cost-benefit judgments) (see Figure 3). The information process of Mindsponge also enabled the exploration into the psycho-religious mechanism of suicidal ideation and suicide attack ^[1211], by further integrating interactions with factors of religious beliefs as well as hostile environmental context.

Figure 3: The mindsponge-based suicidal ideation mechanism

In a study about children’s book reading interest ^[2725], a similar approach was used to examine the mechanism of reading interest in low- and high-achieving students through different thinking pathways. Here, the Mindsponge aspect of cost-benefit judgments helps predict and explain how the sense of autonomy influences children’s attitudes toward their sources of information. This study and other previous psychological research also showed the great compatibility of utilizing the Bayesian analysis with Mindsponge processes. The approach is called Bayesianmindsponge*bayesvl Mindsponge Framework (BMF) analyticsthodology ^[2826][29]. While mindsponge is the name of the framework, bayesvl is the name of the software that performs the analysis of Bayesian models ^{[3027][3128][3229]}.

The miAndsponge mechanism was foundational for establishing the new theory of serendipity. Based on the mechanism, the new theory of serendipity explains how serendipity happens under the information processing perspective and suggests that serendipity is a survival skill that can be cultivated, but not “luck” or “fate” ^[33]. Miother major applicationdsponge is also a cornerstone oof the serendipity-mindsponge-3D knowledge management framework used to explain the information processes of the development, production, and distribution of COVID-19 vaccines ^[34]. Another crucial application of the mind mechanism is implied in the study assponge mechanism was examinssing the western ideological homogeneity issue within entrepreneurial finance research.^[30], By treating whighly cited papers as the research field’s mindset and the publishing system as the ideological value filters, the authors created a new approach of usere the mindsponge framework is used to derive models for conducting bibliometric analyses (the Y-index and social network analysis) for assessing the state of ideological dominance and ideological heterogeneity tolerance within a research field ^[35]sis.
