Creativity and innovation are essential for solving complex problems, generating novel ideas, and advancing human knowledge. However, they are not the result of individual genius or isolated efforts. Rather, they depend on the interactions and collaborations among diverse people who share their perspectives, insights, and feedback. These interactions and collaborations form a brainstorming network, which is a social structure that facilitates the flow of ideas among its members. A brainstorming network can be seen as a dynamic system that evolves over time, influenced by various factors such as the network size, composition, density, centrality, and diversity. Understanding how these factors affect the quality and quantity of ideas generated by a brainstorming network can help us design and optimize strategies for enhancing creativity and innovation.
Some of the strategies for brainstorming networks are:
- 1. Balance the network size and composition. A larger network can provide more diverse and novel ideas, but it can also increase the cognitive load and communication costs for its members. A smaller network can foster more trust and cohesion, but it can also limit the range and variety of ideas. Therefore, it is important to find the optimal network size that maximizes the benefits and minimizes the drawbacks of brainstorming. Moreover, the composition of the network should reflect the goals and objectives of the brainstorming session. For example, if the aim is to generate radical and disruptive ideas, then the network should include members with diverse backgrounds, expertise, and perspectives. If the aim is to refine and improve existing ideas, then the network should include members with relevant knowledge, skills, and experience.
- 2. Increase the network density and centrality. The density of a network refers to the proportion of connections among its members, while the centrality of a network refers to the extent to which some members are more connected than others. A higher network density and centrality can enhance the idea flow and feedback loop within the network, as well as the social capital and trust among its members. However, a too high network density and centrality can also create echo chambers and groupthink, where members tend to conform to the dominant views and opinions of the network. Therefore, it is important to balance the network density and centrality with the network diversity and openness, so that the network can benefit from both internal and external sources of ideas and information.
- 3. Leverage the network diversity and openness. The diversity of a network refers to the degree of heterogeneity and variety among its members, while the openness of a network refers to the degree of accessibility and permeability of its boundaries. A higher network diversity and openness can increase the potential and opportunity for creativity and innovation, as they enable the network to access and combine different types of ideas and information from various domains and sources. However, a too high network diversity and openness can also create conflicts and misunderstandings among the network members, as well as the loss of identity and coherence of the network. Therefore, it is important to balance the network diversity and openness with the network alignment and integration, so that the network can maintain a common vision and direction, as well as a shared language and culture.
An example of a brainstorming network that applied these strategies is the Pixar Braintrust, which is a group of directors, writers, and producers who meet regularly to review and critique each other's work at Pixar Animation Studios. The Pixar Braintrust has a moderate network size and composition, consisting of about a dozen members who have different roles and responsibilities, but share a passion and expertise for storytelling. The Pixar Braintrust has a high network density and centrality, as the members have frequent and direct interactions and communications, as well as strong ties and relationships. The Pixar Braintrust also has a high network diversity and openness, as the members have diverse backgrounds, perspectives, and styles, as well as the freedom and flexibility to explore and experiment with different ideas and approaches. The Pixar Braintrust balances these factors with a clear network alignment and integration, as the members have a common goal and vision, as well as a shared language and culture. The Pixar Braintrust has been credited for the success and innovation of Pixar's films, such as Toy Story, Finding Nemo, The Incredibles, and Inside Out.
One of the main objectives of brainstorming is to generate novel and useful ideas that can be applied to solve problems or create opportunities. However, brainstorming is not a solitary activity; it involves interacting with others who have different perspectives, knowledge, and skills. Therefore, it is important to understand how the structure and dynamics of the network of brainstormers affect the quality and quantity of the ideas produced. In this section, we will discuss how brainstorming networks can enhance three aspects of the creative process: idea generation, evaluation, and implementation.
- Idea generation: Brainstorming networks can facilitate the generation of diverse and original ideas by enabling the exchange of information, feedback, and inspiration among the participants. The network structure can influence the degree of diversity and originality of the ideas by affecting the exposure to different sources of knowledge and stimuli. For example, a network that is dense (i.e., many connections among the nodes) and homogeneous (i.e., similar attributes among the nodes) can foster the convergence of ideas and the reinforcement of existing knowledge, but it may also limit the exploration of new and unconventional possibilities. On the other hand, a network that is sparse (i.e., few connections among the nodes) and heterogeneous (i.e., different attributes among the nodes) can encourage the divergence of ideas and the integration of novel and diverse perspectives, but it may also create challenges for communication and coordination. Therefore, a balance between density and sparsity, and between homogeneity and heterogeneity, is desirable for optimal idea generation. For instance, a small-world network (i.e., a network that has clusters of densely connected nodes that are sparsely connected to other clusters) can combine the benefits of both types of networks by allowing the local exploitation of existing knowledge and the global exploration of new information.
- Idea evaluation: Brainstorming networks can also enhance the evaluation of the ideas generated by providing multiple criteria and perspectives to assess their feasibility, usefulness, and originality. The network structure can influence the degree of rigor and diversity of the evaluation by affecting the availability and quality of the feedback and the criticism received by the idea generators. For example, a network that is centralized (i.e., a network that has one or a few nodes that have many connections to the rest of the nodes) and authoritative (i.e., a network that has nodes that have high status or power over the others) can facilitate the enforcement of standards and norms and the elimination of weak or inappropriate ideas, but it may also discourage dissent and innovation. On the other hand, a network that is decentralized (i.e., a network that has no or few nodes that have many connections to the rest of the nodes) and democratic (i.e., a network that has nodes that have equal or similar status or power) can foster the expression of diverse and original opinions and the inclusion of multiple and alternative ideas, but it may also create conflicts and confusion. Therefore, a balance between centralization and decentralization, and between authority and democracy, is desirable for optimal idea evaluation. For instance, a core-periphery network (i.e., a network that has a core of densely connected nodes that are sparsely connected to a periphery of loosely connected nodes) can combine the benefits of both types of networks by allowing the core to provide guidance and direction and the periphery to provide variety and novelty.
- Idea implementation: Brainstorming networks can also improve the implementation of the ideas evaluated by facilitating the mobilization of resources, support, and collaboration among the participants. The network structure can influence the degree of efficiency and effectiveness of the implementation by affecting the access and distribution of the material and social capital needed to execute the ideas. For example, a network that is closed (i.e., a network that has few or no connections to other networks) and cohesive (i.e., a network that has strong and frequent ties among the nodes) can enhance the commitment and loyalty of the members and the alignment of their goals and values, but it may also isolate them from external opportunities and challenges. On the other hand, a network that is open (i.e., a network that has many connections to other networks) and diverse (i.e., a network that has weak and infrequent ties among the nodes) can increase the exposure and access of the members to different resources and partners, but it may also reduce their trust and solidarity. Therefore, a balance between closure and openness, and between cohesion and diversity, is desirable for optimal idea implementation. For instance, a brokerage network (i.e., a network that has nodes that act as bridges or brokers between otherwise disconnected nodes or networks) can combine the benefits of both types of networks by allowing the brokers to leverage their social capital and connections to facilitate the realization of the ideas.
While brainstorming networks can facilitate the generation and exchange of ideas among individuals, they can also pose some challenges that may hinder the quality, diversity, and flow of ideas. These challenges can be categorized into three main types: cognitive, social, and structural.
- Cognitive challenges refer to the mental processes that affect how individuals perceive, process, and evaluate information. Some examples of cognitive challenges are:
- Confirmation bias: This is the tendency to seek, interpret, and favor information that confirms one's existing beliefs or hypotheses. For instance, if a person believes that electric cars are better than gasoline cars, they may ignore or dismiss any evidence that contradicts this belief, such as the environmental impact of battery production or disposal. Confirmation bias can reduce the diversity and quality of ideas by limiting the exploration of alternative perspectives or solutions.
- Fixation: This is the inability to see a problem from a different angle or to generate novel ideas beyond the obvious or familiar ones. For example, if a person is asked to think of ways to improve a bicycle, they may only focus on modifying the existing features, such as the wheels, the seat, or the handlebars, rather than considering more radical changes, such as adding a motor, a solar panel, or a parachute. Fixation can hinder the flow and quality of ideas by restricting the creativity and originality of the brainstormers.
- Evaluation apprehension: This is the fear of being judged negatively by others for one's ideas or opinions. For instance, if a person has an unconventional or controversial idea, they may hesitate to share it with others, fearing that they will be ridiculed, rejected, or criticized. Evaluation apprehension can inhibit the flow and diversity of ideas by discouraging the expression of novel or risky ideas.
- Social challenges refer to the interpersonal factors that affect how individuals interact, communicate, and collaborate with others. Some examples of social challenges are:
- Groupthink: This is the tendency to conform to the opinions or decisions of the majority or the leader of the group, often at the expense of critical thinking or individual judgment. For example, if a group of engineers is working on a project, they may agree with the proposed solution of the senior engineer, even if they have doubts or reservations about it, because they do not want to challenge their authority or create conflict. Groupthink can reduce the quality and diversity of ideas by suppressing dissenting or divergent views.
- Social loafing: This is the tendency to exert less effort or contribute less when working in a group than when working individually. For instance, if a group of students is assigned to write a report, some of them may rely on others to do most of the work, while they do little or nothing. Social loafing can hinder the flow and quality of ideas by decreasing the motivation and accountability of the group members.
- Free riding: This is the tendency to benefit from the efforts or contributions of others without reciprocating or acknowledging them. For example, if a group of researchers is conducting a study, some of them may use the data or findings of others without citing or crediting them. Free riding can inhibit the flow and diversity of ideas by creating a sense of injustice or resentment among the group members.
- Structural challenges refer to the organizational or environmental factors that affect how individuals access, share, and use information. Some examples of structural challenges are:
- Information overload: This is the exposure to more information than one can process or handle effectively. For instance, if a person is browsing the internet for ideas, they may encounter a vast amount of information from various sources, such as websites, blogs, podcasts, videos, etc. Information overload can reduce the quality and flow of ideas by causing confusion, distraction, or fatigue.
- Information silos: This is the isolation or segregation of information within different departments, units, or domains. For example, if a company is developing a new product, the marketing team may have different information than the engineering team, and they may not communicate or coordinate with each other. Information silos can hinder the diversity and flow of ideas by preventing the integration or synthesis of different perspectives or insights.
- Information asymmetry: This is the unequal distribution or access of information among different parties. For instance, if a group of investors is evaluating a startup, the founders may have more information about the product, the market, or the competitors than the investors, and they may not disclose or reveal all the relevant information. Information asymmetry can inhibit the quality and diversity of ideas by creating a gap or imbalance of power or knowledge.
These challenges of brainstorming networks can be overcome or mitigated by adopting some strategies, such as:
- Encouraging diversity and dissent: This involves inviting and welcoming different opinions, perspectives, and backgrounds, and fostering a culture of constructive criticism and debate. This can help to avoid groupthink, confirmation bias, and information silos, and to enhance the quality and diversity of ideas.
- Providing feedback and recognition: This involves giving and receiving constructive and timely feedback, and acknowledging and rewarding the efforts and contributions of others. This can help to reduce evaluation apprehension, social loafing, and free riding, and to increase the motivation and accountability of the group members.
- Using technology and tools: This involves leveraging the potential of digital platforms, applications, and devices to facilitate the generation, exchange, and management of information. This can help to cope with information overload, information asymmetry, and fixation, and to improve the access, sharing, and use of information.

In this blog, we have explored the concept of brainstorming networks and how they can help us navigate the flow of ideas in our creative endeavors. We have seen how brainstorming networks can be classified into four types: divergent, convergent, hybrid, and dynamic, and how each type has its own advantages and disadvantages. We have also discussed some strategies for choosing and using the best type of brainstorming network for our specific goals and challenges. Here are some of the main points and takeaways from our discussion:
- Brainstorming networks are groups of people who collaborate and exchange ideas on a common topic or problem.
- Brainstorming networks can enhance our creativity, productivity, and innovation by providing us with diverse perspectives, feedback, and inspiration.
- Brainstorming networks can also pose some risks and challenges, such as groupthink, social loafing, evaluation apprehension, and information overload.
- The type of brainstorming network we choose depends on our purpose, context, and preferences. We should consider factors such as the size, diversity, structure, and dynamics of the network, as well as our own personality, style, and goals.
- Divergent brainstorming networks are best for generating a large number of novel and varied ideas. They are characterized by low cohesion, high diversity, and loose structure. Examples of divergent brainstorming networks are brainstorming sessions, online forums, and crowdsourcing platforms.
- Convergent brainstorming networks are best for evaluating and selecting the best ideas from a given pool. They are characterized by high cohesion, low diversity, and tight structure. Examples of convergent brainstorming networks are focus groups, jury panels, and expert committees.
- Hybrid brainstorming networks are best for integrating and combining ideas from different sources. They are characterized by moderate cohesion, moderate diversity, and flexible structure. Examples of hybrid brainstorming networks are cross-functional teams, interdisciplinary groups, and innovation labs.
- Dynamic brainstorming networks are best for adapting and changing ideas according to the evolving situation. They are characterized by variable cohesion, variable diversity, and adaptive structure. Examples of dynamic brainstorming networks are agile teams, crisis management groups, and learning communities.
