The New England Complex Systems Institute (NECSI) is an independent American research institution and think tank dedicated to advancing analytics and its application to the challenges of society, and the interaction of complex systems with the environment. NECSI offers educational programs, conducts research, and hosts the International Conference on Complex Systems. It was founded in 1996 and is located in Cambridge, Massachusetts. [1]
NECSI was established in 1996 by faculty of various New England academic institutions, including MIT, Harvard, Brandeis, and others, to encourage communication and collaboration among researchers studying complex systems. [2]
The NECSI web site describes "complex systems" as follows: [1]
Complex systems have multiple interacting components whose collective behavior cannot be simply inferred from the behavior of components. The recognition that understanding the parts cannot explain collective behavior has led to various new concepts and methodologies that are affecting all fields of science and engineering, and are being applied to technology, business and even social policy.
NECSI promotes collaboration and dissemination of new research among complex systems researchers in wide-ranging disciplines and numerous institutions. NECSI's activities for this purpose include hosting an international research conference and maintaining a roster of affiliated scholars and co-faculty.
NECSI hosts the International Conference on Complex Systems (ICCS), whose aims are:
first, to investigate those properties or characteristics that appear to be common to the very different complex systems now under study; and second, to encourage cross fertilization among the many disciplines involved. [3]
ICCS takes place on an occasional basis, with the most recent (eighth conference) in 2011. ICCS conferences have featured notable computer scientists (e.g., Gerald Sussman), mathematicians (e.g., Stephen Wolfram), systems theorists (e.g., John Sterman), physicists (e.g. Sandy Pentland), economists (e.g., James Stock), and others. Events at ICCS include research presentations and workshops, as well as pedagogical sessions aimed at a wider community.
NECSI provides a public platform for affiliates and co-faculty at numerous academic institutions, primarily in the New England region. These researchers also contribute to NECSI educational programs. [4]
NECSI researchers have contributed to the understanding of evolutionary dynamics, the evolution of altruism, the origin and characterization of biodiversity, and the interplay between evolution and ecology.
Much of the work done at NECSI has focused on the role of the spatial distribution of species, an often overlooked factor of evolutionary dynamics. In the case where portions of a population are geographically isolated from each other, for example, Yaneer Bar-Yam was able to demonstrate shortcomings in the gene-centered view of evolution, an approximation that is valid only if there is complete mixing of alleles in the gene pool. [5]
Studies of network topologies have found surprising similarities between a variety of complex social, technological and biological networks. NECSI research in networks focuses on the relationship between structure, dynamics and function. The study of networks has emerged in diverse disciplines as a means of analyzing complex relational data.
NECSI research in social systems focuses on the collective actions that create revolutions, ethnic violence, urban health, fads and panics, global food and so on. The role of individuals and organization can be analyzed by techniques and tools of complex systems.
Complex systems exhibit behaviors at a variety of spatial and temporal scales. Researchers working at NECSI have developed a mathematical formalism for simultaneously describing systems on multiple scales. This formalism had been applied to physical systems, information systems, organizational behavior, engineering projects and military conflict.
An essential tool for multiscale analysis, the complexity profile, the relationship between the observed complexity of a system and the scale of observation.
Since 2009, the Institute's research focus has shifted to socio-economic systems, with particular attention to the causes and consequences of the 2008 financial crisis and dynamics of Twitter networks and social sentiment. Policy-relevant articles on stock market regulation and market crashes, [6] [7] [8] [9] [10] food riots and the causes of high food prices, [11] [12] [13] and the European bond crisis [14] have been released straight to the press. Peer-reviewed articles continue to appear on other subjects. [15] [16] [17]
NECSI's work on the global food crisis has been widely cited by the press, [18] [19] [20] by movements to curb financial speculation, [21] [22] and included among the top-10 discoveries in science in 2011 by Wired. [23] NECSI's scientific visualizations have received multiple citations on top-10 lists. [24] [25] [26]
NECSI has been called "a pioneer in using mathematics, computation and other quantitative methods to analyse topics like ethnic violence, economic crises and healthcare systems" by the press. [27]
Prior to global lockdowns, in January, 2020 Joseph Norman, Yaneer Bar Yam, and Nassim Taleb submitted a paper to the White House administration, urging them to take drastic steps to curtail the disease. [28] NECSI later assembled EndCoronaVirus.org, which included over 4,000 volunteers by March 21, 2020. The network of volunteers built endCoronavirus.org with the goal to minimize the impact of COVID-19 by providing useful data and guidelines for action. [29]
Social dynamics is the study of the behavior of groups that results from the interactions of individual group members as well to the study of the relationship between individual interactions and group level behaviors.
A complex system is a system composed of many components which may interact with each other. Examples of complex systems are Earth's global climate, organisms, the human brain, infrastructure such as power grid, transportation or communication systems, complex software and electronic systems, social and economic organizations, an ecosystem, a living cell, and ultimately the entire universe.
A stock market crash is a sudden dramatic decline of stock prices across a major cross-section of a stock market, resulting in a significant loss of paper wealth. Crashes are driven by panic selling and underlying economic factors. They often follow speculation and economic bubbles.
Econophysics is a heterodox interdisciplinary research field, applying theories and methods originally developed by physicists in order to solve problems in economics, usually those including uncertainty or stochastic processes and nonlinear dynamics. Some of its application to the study of financial markets has also been termed statistical finance referring to its roots in statistical physics. Econophysics is closely related to social physics.
Ethnic violence is a form of political violence expressly motivated by ethnic hatred and ethnic conflict. Forms of ethnic violence which can be argued to have the character of terrorism may be known as ethnic terrorism or ethnically-motivated terrorism. "Racist terrorism" is a form of ethnic violence dominated by overt racism and xenophobic reactionism.
System of systems is a collection of task-oriented or dedicated systems that pool their resources and capabilities together to create a new, more complex system which offers more functionality and performance than simply the sum of the constituent systems. Currently, systems of systems is a critical research discipline for which frames of reference, thought processes, quantitative analysis, tools, and design methods are incomplete. The methodology for defining, abstracting, modeling, and analyzing system of systems problems is typically referred to as system of systems engineering.
Nassim Nicholas Taleb is a Lebanese-American essayist, mathematical statistician, former option trader, risk analyst, and aphorist whose work concerns problems of randomness, probability, and uncertainty. The Sunday Times called his 2007 book The Black Swan one of the 12 most influential books since World War II.
A complex adaptive system is a system that is complex in that it is a dynamic network of interactions, but the behavior of the ensemble may not be predictable according to the behavior of the components. It is adaptive in that the individual and collective behavior mutate and self-organize corresponding to the change-initiating micro-event or collection of events. It is a "complex macroscopic collection" of relatively "similar and partially connected micro-structures" formed in order to adapt to the changing environment and increase their survivability as a macro-structure. The Complex Adaptive Systems approach builds on replicator dynamics.

Erik Rauch was an American biophysicist and theoretical ecologist who worked at NECSI, MIT, Santa Fe Institute, Yale University, Princeton University, and other institutions. Rauch's most notable paper was published in Nature and concerned the mathematical modeling of the conservation of biodiversity.
Complexity theory and organizations, also called complexity strategy or complex adaptive organizations, is the use of the study of complexity systems in the field of strategic management and organizational studies. It draws from research in the natural sciences that examines uncertainty and non-linearity. Complexity theory emphasizes interactions and the accompanying feedback loops that constantly change systems. While it proposes that systems are unpredictable, they are also constrained by order-generating rules.
Yaneer Bar-Yam is an American scientist and activist specializing in complex systems. An expert in the quantitative analysis of pandemics, he advised policy makers on the Western African Ebola virus epidemic and founded EndCoronavirus.org, a global network of over 4,000 volunteers formed in February 2020 to provide information, guidelines, and policy advocacy to fight the COVID-19 pandemic. He is the founding president of the New England Complex Systems Institute (NECSI), an independent research institution that studies complex systems science and its real-world applications.
Public safety agencies at various levels of government have joined together to share information and communicate when faced with public safety incidents. Interagency collaboration initiatives of this nature result in the creation of public safety networks. Public safety networks may originate at any level of government, and their user base may span a single or multiple geographies. Such a network of public safety agencies, supported by an information and communications technology infrastructure, emerges from the individual and collaborative behaviors of their member agencies.

Antifragile: Things That Gain From Disorder is a book by Nassim Nicholas Taleb published on November 27, 2012, by Random House in the United States and Penguin in the United Kingdom. This book builds upon ideas from his previous works including Fooled by Randomness (2001), The Black Swan (2007–2010), and The Bed of Procrustes (2010–2016) and is the fourth book in the five-volume philosophical treatise on uncertainty titled Incerto. Some of the ideas are expanded in Taleb’s fifth book Skin in the Game: Hidden Asymmetries in Daily Life (2018).
Rare or extreme events are events that occur with low frequency, and often refers to infrequent events that have widespread impact and which might destabilize systems. Rare events encompass natural phenomena, anthropogenic hazards, as well as phenomena for which natural and anthropogenic factors interact in complex ways.
