Diffusion of Innovation
Introduction
Diffusion is the process by which an innovation, which can be a novel concept,
activity, or product, is communicated and spreads over time among members of a social
system. It comprises both knowledge transmission and acceptance of the innovation by
individuals or other entities within the social system. The notion that media messages are
only transferred in two phases has been challenged, with proponents proposing for a more
complex multi-step flow. This line of investigation has led experts to investigate how media
messages spread in society. In 1962, Everett Rogers proposed the Diffusion of Innovation
theory to explore the spread of new ideas or innovations throughout society and the numerous
ways in which people embrace these novel ideas.
Rogers (2003) defines innovation as "an idea, practice, or project perceived as novel
by individuals or other units of adoption." Rogers defines diffusion as the process by which
an innovation is conveyed through certain channels among members of a social system over
time. The decision-making process for innovation has five stages: knowledge, persuasion,
decision, implementation, and confirmation. According to Rogers (1962), individuals in any
given culture can be split into distinct adopter groups based on the pace at which they accept
the innovation.
The KAP Gap
The knowledge-attitude-practice gap (KAP-gap) is a situation in which people have
knowledge and a positive attitude toward an invention but fail to act on it or incorporate it
into their routines.
This gap is frequently seen with preventative technologies, which try to avoid or
reduce the impact of anticipated future catastrophes. (Chantal, 2021) Because the benefits of
implementing preventative innovations are not immediately apparent, individuals may not
feel compelled to act on them, while having a favorable attitude toward the invention.
There is always an expense to changing one's behavior, and if individuals are not
sufficiently motivated to bear that cost, they may choose not to adopt the innovation. In
software engineering, for example, documenting code for improved maintenance may be
viewed as superfluous overhead if future maintenance needs or the developer's role in them
are unknown.
Other best practices that do not provide immediate benefits face a similar situation.
Developers may dispute the utility of devoting time to generating understandable commit
messages because the payoff is not immediately apparent, especially for rookie developers
with a shorter-term perspective. Extrinsic motivators, on the other hand, can be employed to
encourage children into such habits.
Adopter Types
Among the adopter types are innovators, early adopters, early majority, late majority, and
laggards (Rogers, 2003). By categorizing individuals in this way, Rogers aimed to emphasize
different patterns of adoption behavior within a social system. Adopters are classified based
on their innovativeness, which is determined by the time of adoption in comparison to the
population's average adoption time. Rogers categorizes adopters into five groups: innovators,
early adopters, early majority, late majority, and laggards. Each category has unique
properties and contributes to the diffusion process. (Chantal, 2021) Early adopters are
respected by their peers and serve as role models, the early majority adopts just before the
average member, the late majority adopts after the average member, and laggards are oriented
toward tradition and adopt very late.
Innovators
These are daring individuals who want to be the first to test out fresh ideas. They eagerly
seek and welcome change, which makes them natural risk takers. Innovators require little
effort to attract because they are already open to fresh ideas.
Early Adopters
These are thought leaders who like taking on leadership roles and are adaptable. They
realize the importance of innovation and easily embrace new ideas. To reach this
demographic, practical information such as how-to manuals and implementation guidelines
are helpful because they require less convincing.
Early Majority
This is made up of people who adopt new ideas before the ordinary person but are not
necessarily leaders themselves. They are more cautious and require proof that an idea works
before implementing it. Sharing success stories and offering evidence of the innovation's
good results can be compelling in engaging the Early Majority.
Late Majority
It is made up of people who are apprehensive of change and tend to adopt innovations
only after the majority has done so. To persuade the Late Majority, show how many others
have successfully accepted the innovation and provide assurance that it is dependable.
Laggards
These are conventional and conservative people who are resistive to change. They are the
most difficult to persuade. Using data, terror appeals, and leveraging pressure from other
adopter groups can be successful approaches for appealing to Laggards.
Aspects of Diffusion
In the context of diffusion, innovation refers to something viewed as novel by a person or
other unit of adoption. The perception of novelty is crucial, but it does not always imply that
the innovation is genuinely original. It just has to be recognized as such by those who will use
it.
Communication channels
These are the means by which messages are passed from one person to the next. There are
several sorts of communication channels, each having unique qualities in terms of innovation
spread. Rogers distinguishes two types of channels: mass media and interpersonal channels.
Interpersonal channels involve direct connection between individuals, whereas mass media
channels convey messages to a vast audience. Both types of channels are crucial in the
diffusion process.
Time
Because the process of diffusion takes time, time is an important factor. It is useful in
understanding how people progressively modify their knowledge, attitudes, and behavior in
response to an invention. Time is also used to divide adopters into groups based on when they
embrace the innovation and to calculate the adoption rate.
Social System
Diffusion occurs within a social system, which can be defined as a collection of
interconnected components, such as individuals, informal groups, organizations, or
subsystems, that collaborate to achieve a common purpose. Within a social system, diffusion
research distinguishes between social structure and communication structure. The values,
norms, roles, and hierarchies that impact diffusion are referred to as social structure, whereas
communication structure governs how messages move across the social system by forming
communication links.
The Innovation-Decision Process
The decision-making process for adopting or rejecting an invention is described by
the innovation-decision process. It is divided into five stages: knowledge, persuasion,
decision, implementation, and confirmation. Individuals become aware of the invention,
create an attitude about it, decide whether to embrace it, begin utilizing it, and continue to
receive knowledge to support or challenge their decision. (LaMorte, 2022). Individuals may
reject the innovation at each level, resulting in a knowledge-attitude-practice gap in which
they are aware of the innovation and have a positive attitude toward it but do not take action
to adopt it.
Steps to the Innovation-Decision Process
The rate of adoption of an innovation is influenced by its attributes, as perceived by
potential adopters. Rogers identifies five attributes: relative advantage, compatibility,
complexity, trialability, and observability. (Singer, 2020) These attributes determine how
potential adopters perceive the innovation and can affect its adoption rate. For example, an
innovation with a higher perceived relative advantage and compatibility is more likely to be
adopted.
Rogers lists five characteristics of innovations that have a significant impact on whether
and how quickly an idea is accepted. He emphasizes that these do not have to be genuine
qualities of an innovation; what matters is how a potential user sees the innovation. These
five attributes have been found to determine about half of the variance of adoption rates.
Relative Advantage
An innovation's perceived relative advantage is the degree to which it is regarded to
improve on a previous innovation. This can take the form of increased profitability or social
status, for example. Preventive innovations are believed to have a relatively low relative
advantage since their impacts may not be immediately obvious or may never materialize
because their objective is to avert an undesired event. (LaMorte, 2022). Incentives (such as
money or free samples) can be used to boost an innovation's perceived relative advantage.
Adoptions motivated by incentives, on the other hand, may be less sustainable, with adopters
potentially rejecting the innovation once the incentive is no longer available. The rate of
adoption of an innovation is positively related to relative advantage.
Compatibility
An innovation's perceived compatibility indicates how consistent it is with an individual's
values, experiences, and requirements. The degree of compatibility determines the behavioral
shift required to implement an invention. Thus, rather than bringing an incompatible
innovation into a social system, adoption may be facilitated if the innovation is divided into
numerous more compatible inventions that can be accepted sequentially — each requiring
only a tiny behavioral modification. Compatibility is connected to the rate of acceptance of
an innovation.
Complexity
The perceived complexity of an innovation refers to how difficult it appears to be to
understand and apply the innovation. A high level of complexity can be a significant obstacle
to adoption. The rate of acceptance of an innovation is adversely proportional to its
complexity.
Trialability
The perceived trialability of an innovation refers to the extent to which it can be tried on a
trial basis. A firsthand trial of an idea is a good method to lessen doubt about it. As a result,
trialability is related to the rate of adoption of an idea.
Observability
The perceived observability of an innovation is the degree to which others can observe
the results of an innovation. Observing a peer can be a proxy for a trial of an innovation.
Observability is positively related to an innovation’s rate of adoption.
Diffusion Networks
Diffusion networks are the social systems or networks via which an innovation spreads.
Several significant diffusion network principles are discussed:
Weak Ties
Weak ties are connections or relationships between people who are not closely related or
in regular contact. These weak linkages play an important role in the spread of innovations.
Individuals with weak relationships to various social networks might introduce innovators to
new ideas and innovations, hence broadening the diffusion process's reach.
Opinion Leaders
People who are influential in their social networks and have a significant influence on
other people's adoption decisions are considered opinion leaders. (Singer, 2020) They are
typically the first to adopt new technologies and serve as role models or information sources
for others. Opinion leaders affect the early majority's adoption decisions by presenting an
innovation's advantages and benefits.
Social Learning
Social learning is the process of acquiring knowledge, attitudes, and actions through
observation and interaction with others in a social context. Social learning is critical in the
formation of diffusion networks. Individuals observe and learn from their peers who have
already adopted an idea, which can influence their own decisions to do so.
Critical Mass
The term critical mass refers to the point at which an innovation is adopted by a
significant number of people within a social system. When a critical mass of adopters is
reached, the diffusion process speeds up, and the innovation is more generally accepted and
adopted by the late majority and laggards. Peer pressure and economic need can both
contribute to the late majority and laggards adopting an innovation.
Conclusion
Various communication channels are used throughout the diffusion process to convey
innovations among members of a social system. The innovation-decision process describes
the stages that people go through while deciding whether or not to accept an idea. It starts
with learning about the innovation, having an opinion about it, and deciding whether or not to
accept it. Individuals participate in practice and learning after adoption to eliminate lingering
ambiguity. They are also continuing to monitor the adoption to ensure that it remains
relevant. Diffusion research has identified types of adopters and features of innovations that
can provide insight into the likelihood of adoption in various settings. Social networks have a
tremendous impact on the adoption process.
